Question 1

A patient is to receive enalapril (Vasotec) 5 mg IV every 6 hours. Each dose is given over 5 minutes. The medication is available in an injectable form, 1.25 mg/mL. How many milliliters of medication will the nurse draw up for each dose?

4 mL
1.25 mg : 1 mL :: 5 mg : x mL
(1.25 × x) = (1 × 5); 1.25x = 5; x = 4

Accepted Answer

4 mL&#10;1.25 mg : 1 mL :: 5 mg : x mL&#10;(1.25 &#215; x) = (1 &#215; 5); 1.25x = 5; x = 4

Question 2

A pregnant woman is experiencing hypertension. The nurse knows that which drug is commonly used for a pregnant patient who is experiencing hypertension?&#10;A) mannitol ( Osmitrol )&#10;B) enalapril ( Vasotec )&#10;C) hydrochlorothiazide ( HydroDIURIL )&#10;D) methyldopa ( Aldomet )

Accepted Answer

Methyldopa is used in the treatment of hypertension during pregnancy. The other options are incorrect.

Question 3

A patient with severe liver disease is receiving the angiotensin converting enzyme (ACE) inhibitor, captopril (Capoten). The nurse is aware that the advantage of this drug for this patient is which characteristic?

A) Captopril rarely causes first-dose hypotensive effects.
B) Captopril has little effect on electrolyte levels.
C) Captopril is a prodrug and is metabolized by the liver before becoming active.
D) Captopril is not a prodrug and does not need to be metabolized by the liver before becoming active.

Accepted Answer

A prodrug relies on a functioning liver to be converted to its active form. Captopril is not a prodrug, and therefore it would be safer for the patient with liver dysfunction.

Question 4

When teaching a patient about antihypertensive drug therapy, which statements by the nurse are correct? (Select all that apply.)&#10;A) &#34;You need to have your blood pressure checked once a week and keep track of the readings.&#34;&#10;B) &#34;If you notice that the symptoms have gone away, you should be able to stop taking the drug.&#34;&#10;C) &#34;An exercise program may be helpful in treating hypertension, but let's check with your doctor first.&#34;&#10;D) &#34;If you experience severe side effects, stop the medicine and let us know at your next office visit.&#34;&#10;E) &#34;Most over-the-counter decongestants are compatible with antihypertensive drugs.&#34;&#10;F) &#34;Please continue taking the medication, even if you are feeling better.&#34;

Accepted Answer

Keeping a record of weekly blood pressure checks helps to monitor the effectiveness of the therapy. Remind the patient not to stop taking the medication just because he or she is feeling better. Abruptly stopping the medication may lead to rebound hypertension. Therapy is often life-long, even though symptoms may improve. Many over-the-counter drugs, especially decongestants, have serious interactions with antihypertensive drugs. The patient needs to consult his or her prescriber before taking any other medication.

Question 5

The nurse is reviewing the JNC 7 guidelines for treatment of hypertension. Which blood pressure would be classified as &#34;prehypertension&#34; according to the JNC 7 guidelines?&#10;A) 118/76 mm Hg&#10;B) 130/88 mm Hg&#10;C) 150/90 mm Hg&#10;D) 160/104 mm Hg

Accepted Answer

Prehypertension is defined as having a systolic blood pressure between 120 and 139 mm Hg and a diastolic pressure between 80 and 89 mm Hg. The other parameters listed are incorrect.

Question 6

A patient who has been taking antihypertensive drugs for a few months complains of having a persistent dry cough. The nurse knows that this cough is an adverse effect of which class of antihypertensive drugs?

A) Beta blockers
B) Angiotensin-converting enzyme (ACE) inhibitors
C) Angiotensin II receptor blockers (ARBs)
D) Calcium channel blockers

Accepted Answer

ACE inhibitors cause a characteristic dry, nonproductive cough that reverses when therapy is stopped. The other drug classes do not cause this cough.

Question 7

A patient's blood pressure elevates to 270/150 mm Hg, and a hypertensive emergency is obvious. He is transferred to the intensive care unit and started on a sodium nitroprusside (Nipride) drip to be titrated per his response. With this medication, the nurse knows that the maximum dose of this drug should be infused for how long?

A) 10 minutes
B) 30 minutes
C) 1 hour
D) 24 hours

Accepted Answer

Sodium nitroprusside is a potent vasodilator and may lead to extreme decreases in the patient's blood pressure. For this reason, it is never infused at the maximum dose for more than 10 minutes. If this drug does not control a patient's blood pressure after 10 minutes, it will most likely be ordered to be discontinued. The other times listed are incorrect.

Question 8

The nurse is reviewing the orders for a patient and notes a new order for an angiotensin-converting enzyme (ACE) inhibitor. The nurse checks the current medication orders, knowing that this drug class may have a serious interaction with what other drug class?

A) Calcium channel blockers
B) Diuretics
C) Nonsteroidal antiinflammatory drugs
D) Nitrates

Accepted Answer

Nonsteroidal antiinflammatory drugs (NSAIDs) such as ibuprofen can reduce the antihypertensive effect of ACE inhibitors. In addition, the use of NSAIDs and ACE inhibitors may also predispose patients to the development of acute renal failure.

Question 9

A patient with type 2 diabetes mellitus has been found to have trace proteinuria. The prescriber writes an order for an angiotensin-converting enzyme (ACE) inhibitor. What is the main reason for prescribing this class of drug for this patient?

A) Cardioprotective effects
B) Renal protective effects
C) Reduces blood pressure
D) Promotes fluid output

Accepted Answer

ACE inhibitors have been shown to have a protective effect on the kidneys because they reduce glomerular filtration pressure. This is one reason that they are among the cardiovascular drugs of choice for diabetic patients. The other drugs do not have this effect.

Question 10

When counseling a male patient about the possible adverse effects of antihypertensive drugs, the nurse will discuss which potential problem?&#10;A) Impotence&#10;B) Bradycardia&#10;C) Increased libido&#10;D) Weight gain

Accepted Answer

Sexual dysfunction is a common complication of antihypertensive medications and may be manifested in men as decreased libido or impotence. The other options are incorrect.

Question 11

A patient with primary hypertension is prescribed drug therapy for the first time. The patient asks how long drug therapy will be needed. Which resolve by the nurse is the correct response?&#10;A) &#34;This therapy will take about 3 months.&#34;&#10;B) &#34;This therapy will take about a year.&#34;&#10;C) &#34;This therapy will go on until your symptoms disappear.&#34;&#10;D) &#34;Therapy for high blood pressure is usually lifelong.&#34;

Accepted Answer

The answer of A patient with primary hypertension is prescribed...

Question 12

During a follow-up visit, the health care provider examines the fundus of the patient's eye. Afterward, the patient asks the nurse, "Why is he looking at my eyes when I have high blood pressure? It does not make sense to me!" What is the best response by the nurse?

A) "We need to monitor for drug toxicity."
B) "We must watch for increased intraocular pressure."
C) "The provider is assessing for visual changes that may occur with drug therapy."
D) "The provider is making sure the treatment is effective over the long-term."
