1. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

2. A nurse is teaching a client with type 2 diabetes about the importance of foot care. Which statement by the client indicates a need for further teaching?

• A. I should check my feet every day for cuts or blisters.
• B. I need to moisturize my feet daily, especially between my toes.
• C. I should wear comfortable shoes that fit well.
• D. I should avoid walking barefoot, even indoors.

Correct answer: B

Rationale: The correct answer is B. Moisturizing between the toes can create a moist environment that fosters fungal infections. Checking the feet daily for cuts or blisters (choice A) is correct in diabetes management to prevent complications. Wearing comfortable shoes that fit well (choice C) and avoiding walking barefoot (choice D) are also essential in preventing foot ulcers and injuries in diabetic patients.

3. When obtaining a rectal temperature with an electronic thermometer, which action is most important for the nurse to perform?

• A. Hold the thermometer in place.
• B. Place the disposable pad under the buttocks.
• C. Instruct the client to breathe deeply.
• D. Return the probe to the charger.

Correct answer: A

Rationale: When obtaining a rectal temperature with an electronic thermometer, holding the thermometer in place is crucial. This action ensures accurate temperature measurement and prevents injury to the client. Option B, placing a disposable pad under the buttocks, is not the most important action; it may enhance comfort but does not impact the accuracy of the temperature reading. Option C, instructing the client to breathe deeply, is irrelevant to obtaining a rectal temperature. Option D, returning the probe to the charger, is an incorrect action after temperature measurement.

4. Which class of drugs is the only source of a cure for septic shock?

• A. Antihypertensives
• B. Anti-infectives
• C. Antihistamines
• D. Anticholesteremics

Correct answer: B

Rationale: The correct answer is B: Anti-infectives. Anti-infective agents, such as antibiotics, are essential in treating septic shock as they can eliminate bacteria and halt the progression of the condition by stopping the production of endotoxins. Antihypertensives (Choice A) are used to lower blood pressure, antihistamines (Choice C) are used to treat allergic reactions, and anticholesteremics (Choice D) are used to lower cholesterol levels. However, none of these drug classes directly address the bacterial infection that underlies septic shock.

5. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which assessment finding is most concerning?

• A. Increased fatigue
• B. Elevated blood pressure
• C. Low urine output
• D. Elevated hemoglobin

Correct answer: B

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, an elevated blood pressure is the most concerning assessment finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention. Increased fatigue may be expected due to anemia associated with CKD and erythropoietin therapy. Low urine output may indicate impaired kidney function but is not as immediately concerning as elevated blood pressure. Elevated hemoglobin levels are the desired outcome of erythropoietin therapy, indicating an appropriate response to treatment.
