Correct Answer: C

Rationale: The correct first action for the nurse when a client expresses anxiety about a procedure is to encourage the client to discuss their fears. By allowing the client to express their concerns, the nurse can provide personalized support, address specific worries, and offer tailored information. This approach helps to establish trust, reduce anxiety, and promote a therapeutic nurse-client relationship. Offering information about the procedure steps (Choice A) may be helpful but should come after addressing the client's fears. Administering an anxiolytic (Choice B) should not be the first action as it focuses on symptom management rather than addressing the underlying cause of anxiety. Reassuring the client that the procedure is common and safe (Choice D) is important but should follow active listening and addressing the client's fears.

Correct Answer: C

Rationale: The correct answer is C. LPNs are trained to provide basic nursing care such as wound care. Providing wound care for a stage III pressure ulcer falls within the LPN's scope of practice. Administering IV medication (choice A) requires a higher level of skill and is usually the responsibility of registered nurses. Conducting initial client assessments (choice B) demands more advanced training and is typically performed by registered nurses. Teaching a diabetic client about insulin administration (choice D) involves patient education and is usually within the scope of registered nurses or other healthcare professionals with specific training in diabetic care.

Correct Answer: B

Rationale: The most important intervention to prevent infection when caring for a client with a urinary catheter is to ensure that the catheter bag is below the level of the bladder. This positioning helps prevent urine backflow, reducing the risk of infection. While using sterile technique for catheter care (Choice A) is important, ensuring proper drainage by keeping the catheter bag below the bladder is crucial to prevent infection. Providing perineal care daily (Choice C) is essential for hygiene but not directly related to preventing catheter-related infections. Changing the catheter only when necessary (Choice D) is important for maintenance, but correct positioning of the catheter bag is more critical in preventing immediate infection.

Correct Answer: C

Rationale: The correct answer is to count the apical pulse rate for sixty seconds. The apical pulse is more accurate, especially when peripheral pulses are weak or irregular. Counting the apical pulse for a full minute provides a more precise heart rate measurement. Option A is incorrect because waiting for thirty minutes is unnecessary and could delay potential interventions. Option B is incorrect because doubling the radial pulse rate may not provide an accurate representation of the heart rate. Option D is incorrect because comparing radial pulses bilaterally does not give the most accurate heart rate measurement; the apical pulse is preferred in this situation.

Correct Answer: C

Rationale: The correct answer is C: Persistent cough. Lisinopril is an ACE inhibitor commonly associated with a persistent dry cough as a side effect. This cough is thought to result from increased bradykinin levels. Choices A, B, and D are incorrect. Hypokalemia is not a common side effect of lisinopril; in fact, it may lead to hyperkalemia. Hyperglycemia is not a typical side effect of lisinopril use. Tachycardia is also not a common side effect associated with ACE inhibitors like lisinopril.
