Correct Answer: A

Rationale: The correct answer is A: Heart rate 56/min. Metoprolol, a beta blocker, should be withheld if the client's heart rate is below 60/min to prevent further bradycardia. Choices B, C, and D are within normal ranges and do not indicate a need to withhold metoprolol.

Correct Answer: A

Rationale: After removing an IV catheter due to phlebitis, the next step is to apply a warm compress over the IV site. This helps reduce inflammation and discomfort for the client. Recording the findings in the client's chart is important for documentation purposes but not the immediate next step. Notifying the client's primary care provider may be necessary depending on the severity of the phlebitis, but it is not the initial action. Inserting a new IV catheter is not appropriate until the phlebitis has resolved.

Correct Answer: C

Rationale: Performing a wound culture before applying ointment is crucial when providing wound care to a client with a pressure ulcer. This action helps identify any underlying infections, allowing healthcare providers to select the most appropriate treatment. Options A, B, and D are not as critical as performing a wound culture, as they focus on wound dressing and cleansing rather than identifying potential infections.

Correct Answer: B

Rationale: The correct answer is B: 'Wear shoes that fit properly.' In peripheral arterial disease (PAD), it is crucial to wear shoes that fit well to prevent foot injuries. Choice A is incorrect because applying lotion between the toes can increase the risk of infection. Choice C is incorrect since walking barefoot at home can lead to injuries, especially in individuals with PAD. Choice D is incorrect as applying ice to the feet daily can further reduce blood flow to the extremities, worsening the condition in PAD.

Correct Answer: A

Rationale: The correct answer is A: Clean the perineal area with soap and water. This step is essential in preventing infection and promoting hygiene. Using antiseptic wipes (choice B) is not a standard practice for perineal care; soap and water are preferred. While patting the area dry after cleaning (choice C) is important, the initial step of cleaning with soap and water is crucial. Using gloves (choice D) is a good practice to prevent the spread of infection, but it is not the initial step in providing perineal care.
