Question 1

A patient's assessment findings suggest infection by a rickettsiae organism. The nurse would ask about which history? Note: Credit will be given only if all correct choices and no incorrect choices are selected.
Standard Text: Select all that apply.

Accepted Answer

Infection by rickettsiae organisms is commonly transmitted by ticks and fleas. Therefore, the nurse would ask about a history of tick bites or exposure to animals with fleas to help identify the possible source of infection. Choices B, C, and E are not relevant to rickettsiae infection.

Question 2

The nurse is caring for a patient in droplet precautions. What protective gear should the nurse wear when providing care to this patient?

Accepted Answer

Droplet precautions require the use of a mask and eye protection or face shield to protect the nurse from droplets that may be expelled during coughing, sneezing, or talking by the patient. Gloves, head coverings, and shoe coverings are not required for droplet precautions.

Question 3

A patient who was diagnosed with an infection is prescribed a macrolide antibiotic. What should the nurse instruct the patient about taking this medication?

Accepted Answer

Macrolide antibiotics should be taken on an empty stomach unless otherwise instructed by the healthcare provider. Food can decrease absorption of the medication, leading to decreased effectiveness. Taking the medication with a full glass of water is appropriate to ensure adequate hydration.

Question 4

A patient who changes her own skin lesion dressings tells the nurse that she developed a new skin lesion on another body part. The nurse realizes this patient is most likely describing which mode of transmission?

Accepted Answer

The description of the patient changing her own skin lesion dressings indicates that she already has a pre-existing skin lesion, which suggests that the new lesion is likely a result of indirect contact transmission, such as touching contaminated surfaces or objects. Vector-borne transmission refers to diseases transmitted through a living carrier, such as mosquitos transmitting malaria. Vehicle transmission refers to the spread of disease through contaminated food, water, or other substances. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person. None of these options fit the scenario described by the patient.

Question 5

The nurse is performing hand hygiene with an alcohol-based product. The nurse should rub the hands together for at least ______ seconds.

Accepted Answer

The answer of The nurse is performing hand hygiene with...

Question 6

A patient with an infection of the wrist and forearm is to wear a splint. The nurse identifies which rationale for this intervention?

Accepted Answer

Wearing a splint can support the limb and provide additional stability to prevent further injury or loss of function due to pain and swelling. A splint is not used to directly stop exudate or pus formation, decrease white blood cell count, or reduce redness.

Question 7

The nurse is caring for four patients in a medical-surgical unit. Which patient should the nurse see first?

Accepted Answer

The patient with infectious gastroenteritis who has had severe diarrhea for the last 24 hours should be seen first as they are at risk for dehydration and electrolyte imbalance.

Question 8

The nurse would assess that a patient is severely neutropenic if the absolute neutrophil count is less than ______ cells per cubic millimeter.

Accepted Answer

The answer of The nurse would assess that a patient...

Question 9

A patient asks the nurse why the infected area on his arm is so red. How should the nurse respond?

Accepted Answer

The redness in the infected area is due to the body increasing the blood supply to the area as a response to the infection. This increased blood flow brings immune cells and nutrients to the area to help fight off the infection.

Question 10

A patient tells the nurse that she doesn't wash her hands very much because the skin on her hands is dry and cracked. What instruction should the nurse give this patient?

Accepted Answer

Using a hand lotion with high fat or oil content will help protect the skin from drying and cracking while still allowing the patient to maintain good hand hygiene. Washing with hot water can further dry out the skin and washing with cold water may not be as effective in removing microbes. Washing without soap may also not effectively remove microbes from the hands.

Quiz 14: Infectious Process and Prophylaxis
