Correct Answer: B

Rationale: The correct answer is to suction the tracheostomy. When a client with a tracheostomy is experiencing respiratory distress, the priority intervention is to clear the airway by suctioning the tracheostomy to remove secretions that may be obstructing the air passage. Administering a bronchodilator (Choice A) may be considered if bronchospasm is present, but the immediate focus should be on clearing the airway. Notifying the physician (Choice C) is important but should not delay the immediate intervention of suctioning. Increasing the oxygen flow rate (Choice D) may provide temporary relief, but addressing the root cause of the distress by suctioning is the priority.

Correct Answer: A

Rationale: A WBC count of 2,900/mm3 indicates leukopenia, which is a serious side effect of clozapine and contraindicates its use. Leukopenia is a significant concern with clozapine therapy due to the risk of agranulocytosis, a potentially life-threatening condition. Monitoring the WBC count is crucial to detect this adverse effect early. The other options (B, C, and D) are within normal ranges and not contraindications for administering clozapine.

Correct Answer: D

Rationale: The correct answer is to replace the NG tube with a new one. When a client with an NG tube experiences nausea and decreased gastric secretions, it indicates a possible problem with the tube itself. Replacing the tube ensures proper functioning and can alleviate the symptoms. Increasing the suction pressure (Choice A) can worsen the client's condition. Turning the client onto their side (Choice B) may be helpful in some situations but does not address the underlying issue. Irrigating the NG tube with sterile water (Choice C) is not the priority and may not resolve the problem.

Correct Answer: A

Rationale: The correct answer is A: "Left-sided: Pulmonary congestion; Right-sided: Systemic edema." Left-sided heart failure primarily affects the lungs, leading to pulmonary congestion, which manifests as symptoms like shortness of breath and cough. On the other hand, right-sided heart failure causes systemic congestion and edema, often presenting as swelling in the legs and abdomen due to fluid retention. Choice B is incorrect because it swaps the features of left-sided and right-sided heart failure. Choice C is incorrect as it also incorrectly switches the characteristics of the two types of heart failure. Choice D is incorrect because it inaccurately associates left-sided heart failure with pulmonary congestion and right-sided heart failure with heart failure itself, which is not a distinguishing feature.

Correct Answer: A

Rationale: When managing care for a patient with a wound infection, administering prescribed antibiotics is crucial. Antibiotics are necessary to treat the infection and prevent it from worsening. While cleaning the wound with saline and applying a sterile dressing are important components of wound care, the primary treatment for a wound infection is antibiotics. Monitoring for signs of sepsis is also essential, but administering antibiotics promptly is the most critical step in managing a wound infection.
