The nurse is preparing to administer a tuberculin skin test (TST). Which area of the body is the preferred site for this injection?

A. Deltoid muscle

B. Inner forearm

C. Abdomen

D. Thigh

Correct Answer: B
Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.

A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure.
• B. Assess heart rate.
• C. Monitor respiratory rate.
• D. Measure oxygen saturation.

Correct Answer: B
Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.

The nurse is assessing a client with left-sided heart failure. Which symptom should the nurse expect to find?

• A. Peripheral edema
• B. Jugular vein distention
• C. Shortness of breath
• D. Weight gain

Correct Answer: C
Rationale: Shortness of breath is a characteristic symptom of left-sided heart failure. In this condition, the heart's inability to effectively pump blood forward causes blood to back up into the lungs, leading to fluid accumulation. This fluid accumulation results in pulmonary congestion, manifesting as shortness of breath or difficulty breathing. Peripheral edema (choice A) is more commonly associated with right-sided heart failure, where fluid accumulates in the extremities. Jugular vein distention (choice B) is a sign of increased central venous pressure and is more indicative of right-sided heart failure. Weight gain (choice D) can be a general symptom of heart failure due to fluid retention, but shortness of breath is specifically related to left-sided heart failure.

The unlicensed assistive personnel (UAP) reports to the nurse that a client refused to bathe for the third consecutive day. What action is best for the nurse to take?

• A. Ask the client why the bath was refused
• B. Ask family members to encourage the client to bathe
• C. Explain the importance of good hygiene to the client
• D. Reschedule the bath for the following day

Correct Answer: A
Rationale: The correct action for the nurse to take is to ask the client why the bath was refused. Understanding the client's reasons for refusal can guide appropriate interventions, respecting client autonomy while addressing any underlying issues. Choice B is not the best course of action as involving family members may not address the client's specific concerns. Choice C, while important, may not directly address the immediate refusal to bathe. Choice D does not address the underlying reasons for the refusal and may not lead to a resolution.

The nurse is caring for a client with chronic liver disease. Which lab value is most concerning?

• A. Elevated AST and ALT
• B. Decreased albumin level
• C. Elevated bilirubin level
• D. Prolonged PT/INR

Correct Answer: D
Rationale: The correct answer is D, prolonged PT/INR. In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This indicates impaired liver function, leading to a higher risk of bleeding. Elevated AST and ALT (choice A) are indicators of liver damage but do not directly assess the risk of bleeding. Decreased albumin level (choice B) reflects impaired liver function but is not as directly related to bleeding risk as a prolonged PT/INR. Elevated bilirubin level (choice C) is a sign of liver dysfunction, specifically related to bile metabolism, and while important, it is not as directly associated with bleeding risk as a prolonged PT/INR in the context of chronic liver disease.
