Correct Answer: A

Rationale: The most important nursing action when a patient has a central line is to monitor for infection. Central line-associated bloodstream infections are a serious complication that can lead to severe outcomes. Monitoring for infection involves assessing the patient for signs and symptoms such as fever, chills, and hypotension. While monitoring the central line dressing, redness, and swelling are also important aspects of care, they are secondary to monitoring for infection as the primary focus should be on preventing serious complications.

Correct Answer: C

Rationale: Dependent edema is a common finding in clients with pneumonia due to fluid retention and decreased mobility. Bradycardia (Choice A) is not typically associated with pneumonia. Crackles in the lung bases (Choice B) are more commonly heard in conditions like heart failure or pulmonary edema. A productive cough (Choice D) can be seen in pneumonia but is not as specific as dependent edema.

Correct Answer: D

Rationale: When a nurse notes early decelerations in electronic fetal monitoring, it indicates head compression, which is generally considered benign and not associated with fetal hypoxia, abruptio placentae, or post maturity. Early decelerations mirror the uterine contractions and are a normal response to fetal head compression during labor.

Correct Answer: B

Rationale: The correct answer is B: Apply a hydrocolloid dressing. Applying a hydrocolloid dressing helps create a moist environment that promotes healing in clients with stage 2 pressure injuries. Choice A, cleansing the wound with povidone-iodine, is not recommended for stage 2 pressure injuries as it can be too harsh on the skin. Performing debridement as needed, as mentioned in choice C, is not typically indicated for stage 2 pressure injuries, which involve partial-thickness skin loss. Keeping the wound open to air, as stated in choice D, is also not the preferred approach for managing stage 2 pressure injuries, as maintaining a moist environment is key to promoting healing.

Correct Answer: C

Rationale: Encouraging the client to increase fluid intake is essential in promoting airway clearance for a client with pneumonia. Increased fluid intake helps thin secretions, making it easier for the client to clear their airways. Chest physiotherapy (Choice A) is more focused on mobilizing secretions and may not be suitable for all clients with pneumonia. Suctioning (Choice B) is indicated for clients who have excessive secretions that they cannot manage effectively themselves. Administering oxygen via nasal cannula (Choice D) is important for clients with pneumonia to maintain adequate oxygenation, but it does not directly promote airway clearance.
