Correct Answer: A

Rationale: Corrected Rationale: A persistent cough is a known adverse effect of enalapril, an ACE inhibitor. Enalapril can cause the accumulation of bradykinin, leading to a dry, persistent cough in some patients. Dry mouth (choice B) and urinary retention (choice C) are not typically associated with enalapril use. Insomnia (choice D) is also not a common adverse effect of enalapril. Therefore, the correct answer is A.

Correct Answer: B

Rationale: Swelling of the arm above the insertion site is concerning as it can indicate complications like thrombosis, which require immediate attention. Redness at the insertion site is common and expected in the initial stages. A bruised area around the insertion site may result from the insertion procedure and is usually not alarming unless it worsens or becomes larger. A temperature of 37.2°C (99°F) is within the normal range and is not directly related to PICC complications.

Correct Answer: D

Rationale: The correct answer is D: 'Keep the wound covered with a dry dressing.' When providing care for a wound infection, it is essential to keep the wound covered with a dry dressing to prevent further contamination and promote healing. Soaking the wound in warm water (choice A) can introduce moisture and increase the risk of infection. Using hydrogen peroxide (choice B) can be too harsh and may slow down the healing process by damaging healthy tissue. Applying a cold compress (choice C) is not typically recommended for wound infections, as it may not provide the necessary environment for healing.

Correct Answer: C

Rationale: The correct answer is C: Jugular vein distention. In left-sided heart failure, the left ventricle fails to efficiently pump blood to the body, causing increased pressure in the pulmonary circulation. This increased pressure can lead to symptoms like jugular vein distention, as blood backs up in the pulmonary circulation and causes congestion. Choices A, B, and D are incorrect: Peripheral edema is more commonly associated with right-sided heart failure, cough with frothy sputum is a sign of pulmonary edema which can occur in left-sided heart failure but is not as specific as jugular vein distention, and dependent edema is also more indicative of right-sided heart failure due to fluid retention and increased venous pressure in the systemic circulation.

Correct Answer: B

Rationale: The correct answer is B: Have the client wear sequential compression devices (SCDs). Following a cholecystectomy, the client is at risk for venous thromboembolism (VTE) due to reduced mobility and surgical stress. SCDs help prevent VTE by promoting venous return and reducing the risk of blood clots. Choices A, C, and D are incorrect. While deep breathing and coughing exercises are essential postoperatively, SCDs take precedence in preventing VTE. Placing the client in a supine position with the head of the bed flat can increase the risk of respiratory complications. Encouraging ambulation is important, but SCDs are a higher priority in this situation to prevent VTE.
