Question 1

Phentolamine is an antidote used for treating hypertensive emergencies caused by catecholamine overdose because it blocks which type of receptors?

Accepted Answer

Phentolamine blocks both alpha1 and alpha2 receptors, which are responsible for the vasoconstrictive effects of catecholamines. It does not block beta receptors.

Question 2

A client is prescribed alfuzosin (Uroxatral)for benign prostatic hyperplasia (BPH).The nurse should anticipate which intended effect of this drug?

Accepted Answer

Alfuzosin is an alpha-1 blocker that relaxes smooth muscle in the prostate and bladder neck, improving urine flow and reducing symptoms of BPH. One common side effect is an increased frequency of urinary excretion. Therefore, the nurse should anticipate this intended effect. Choices A and B are incorrect because they describe potential adverse effects, while choice C is incorrect because alfuzosin does not increase sodium excretion.

Question 3

An older client who is prescribed terazosin (Hytrin)for treatment of benign prostatic hyperplasia (BPH)asks the nurse the reason why this drug should initially be taken at bedtime.Which rationale will the nurse base the response to the client?

Accepted Answer

Terazosin can cause a sudden fall in blood pressure, especially during the first dose or within the first few hours of taking it. By taking it at bedtime, the client can avoid the risk of orthostatic hypotension and falls during the day.

Question 4

Which instruction should the nurse include in the discharge teaching plan of a client being treated with propranolol (Inderal)for angina?

Accepted Answer

It is important for the client to understand that suddenly stopping propranolol can lead to rebound hypertension, angina, and myocardial infarction. The client should always check with their healthcare provider before making any changes to their medication regimen. Choices A, B, and D are all incorrect and potentially harmful instructions. Salt and salt substitutes can decrease the effectiveness of propranolol in managing angina. Taking a double dose can lead to overdose and side effects. Using an OTC medication without consulting with the healthcare provider can potentially interact with propranolol and cause harmful side effects.

Question 5

The nurse should order for propranolol (Inderal)in treatment of hypertension when the client has which associated disorders? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

The answer of The nurse should order for propranolol (Inderal)in...

Question 6

An older adult client who is taking doxazosin (Cardura)for hypertension is given a prescription of sildenafil for erectile dysfunction.The nurse should caution the client about which effect?

Accepted Answer

Sildenafil can potentiate the hypotensive effects of doxazosin, causing a drop in blood pressure that could be dangerous for the client. It is important for the nurse to advise the client to avoid taking sildenafil while on doxazosin or any other antihypertensive medication.

Question 7

In preparing a teaching plan for a client who is on acebutolol (Sectral),the nurse should include which instructions? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

Taking the radial pulse before each dose and reporting any irregular pulse is important as acebutolol may cause heart rhythm disturbances. Reporting cold, painful, or tender feet or hands is necessary as these may be symptoms of peripheral vascular disease, a potential side effect of the drug. It is important to take the medication regularly and not stop it abruptly, which is why option C is incorrect. Option D is also incorrect because stopping the drug completely without consulting a healthcare provider may lead to rebound hypertension.

Question 8

A client diagnosed with hypertension is prescribed atenolol (Tenormin).The nurse knows that this medication is a selective beta₁ blocker and can be safely used for clients with which concurrent diagnosis?

Accepted Answer

The answer of A client diagnosed with hypertension is prescribed...

Question 9

A client diagnosed with hypertension is prescribed carvedilol (Coreg)and complains of dizziness and faintness immediately after taking this medication.The nurse knows that this effect is due to the action of which receptors?

Accepted Answer

Carvedilol is a non-selective beta-adrenergic antagonist that also has alpha-adrenergic blocking activity, meaning it blocks the activation of alpha1 and beta1 and beta2 receptors. This blockade of alpha1 receptors can cause vasodilation, leading to a drop in blood pressure and dizziness/faintness. The blockade of beta1 receptors in the heart can also lower heart rate and cardiac output, contributing to hypotension and dizziness. Beta2 receptors are not usually involved in blood pressure regulation and therefore not relevant in this case. Therefore, the main receptors involved in the dizziness and faintness seen with carvedilol use are alpha1 and beta1.

Question 10

A client is prescribed sotalol (Betapace)for a cardiac dysrhythmia.The nurse knows that sotalol (Betapace)is used in this client because it performs which action?

Accepted Answer

Sotalol (Betapace) is a beta blocker medication that slows the travel of impulses across the myocardium, which can help to control cardiac dysrhythmias. It does not increase renin secretion or decrease sympathetic output, and it may have a slight negative effect on myocardial contractility, but this is not its main mechanism of action.

Question 11

A client prescribed propranolol (Inderal)for angina asks the nurse why this drug should not be abruptly discontinued.The nurse would be correct in telling the client that abrupt withdrawal could lead to which result?

Accepted Answer

Abrupt withdrawal of propranolol can result in rebound chest pain or heart attack due to the sudden increase in heart rate and blood pressure. It is important to gradually taper off the medication under the guidance of a healthcare provider to avoid these potential complications.

Question 12

For which symptoms should the nurse teach the client to monitor when taking doxazosin (Cardura)?

Accepted Answer

Dizziness and headache are common side effects of doxazosin and should be monitored closely by the client. Difficulty in breathing and decreased urinary frequency are not common side effects of doxazosin, and constipation is a possible but less common side effect.

Question 13

The nurse is evaluating a client's response to a newly prescribed adrenergic agonist.Which assessment findings does the nurse anticipate this client will exhibit? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

The answer of The nurse is evaluating a client's response...

Question 14

A client is seen in the clinic for migraine headaches.The nurse anticipates that which medication might be prescribed as a prophylaxis for migraines?

Accepted Answer

Propranolol (Inderal) is a beta-blocker that has been shown to be effective in reducing the frequency and severity of migraines. Acebutolol, carvedilol, and metoprolol are also beta-blockers, but they have not been specifically approved for the prophylaxis of migraines.

Question 15

The nurse is preparing a care plan for an elderly client diagnosed with hypertension,who is prescribed prazosin (Minipress)1 mg 2 times a day.Which instructions should the nurse include in the care plan for this client? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

The answer of The nurse is preparing a care plan...

Question 16

A client is given tamsulosin (Flomax)for benign prostatic hyperplasia (BPH).The nurse knows that the action of this drug is due to selective blockade of which receptor?

Accepted Answer

Tamsulosin (Flomax) selectively blocks alpha1 receptors in the prostate gland, which leads to relaxation of smooth muscle and improved urine flow in patients with BPH.

Question 17

Prazosin (Minipress)is prescribed for hypertensive client.Which measure should be used by the nurse to prevent the first-dose phenomenon?

Accepted Answer

The first-dose phenomenon is characterized by symptoms such as dizziness and fainting that occur soon after the client takes the first dose of medication. It is most commonly associated with the use of alpha-adrenergic blockers such as prazosin. The nurse can prevent this phenomenon by giving the initial low doses of the medication at bedtime, which will allow the client to sleep through any potential adverse effects.

Question 18

A client is to be treated for an overdose of propranolol (Inderal).Which medications should the nurse anticipate being used? Note: Credit will be given only if all correct choices and no incorrect choices are selected.Standard Text: Select all that apply.

Accepted Answer

The answer of A client is to be treated for...

Question 19

Which medication should the nurse anticipate to be prescribed for a client with asthma and hypertension?

Accepted Answer

Beta-blockers like metoprolol are often prescribed for clients with asthma and hypertension because they not only lower blood pressure, but they also can improve lung function and decrease the frequency and severity of asthma symptoms. Propranolol, sotalol, and nadolol are also beta-blockers, but they are not typically used for clients with asthma due to their potential to cause bronchoconstriction.

Question 20

Which symptom is the client who is prescribed alpha₁-antagonist therapy likely to complain of within the first 24 hours?

Accepted Answer

Alpha₁-antagonists are medications used to lower blood pressure by blocking specific receptors that cause blood vessels to constrict. One of the most common side effects of alpha₁-antagonists is orthostatic hypotension, resulting in dizziness and fainting, particularly within the first 24 hours of starting treatment. Difficulty swallowing, blurring of vision, and decreased urinary frequency are not typically associated with alpha₁-antagonist therapy.
