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: Cyanosis of the lips and nail beds. Cyanosis is a late sign of hypoxia and indicates severe oxygen deprivation, requiring immediate intervention in clients with pneumonia. Reporting this finding promptly is crucial to prevent further complications. Choices A, B, and D are incorrect because increased appetite, productive cough with green sputum, and mild shortness of breath are common findings in clients with pneumonia and may not require immediate intervention unless they worsen or are accompanied by other concerning symptoms.

Correct Answer: D

Rationale: The correct statement to include when teaching a client prescribed with lisinopril is that they should avoid using salt substitutes while taking this medication. Lisinopril can cause hyperkalemia, which is an elevated level of potassium in the blood. Therefore, using salt substitutes that contain potassium can worsen this condition. Choices A, B, and C are incorrect because lisinopril is not typically associated with causing a dry cough or a slow heart rate, and increasing potassium intake can be harmful in the presence of lisinopril-induced hyperkalemia.

Correct Answer: A

Rationale: The correct answer is A: Low back pain. Low back pain is a common sign of a hemolytic transfusion reaction, indicating the destruction of red blood cells. This finding requires immediate intervention as it can lead to serious complications such as renal failure. Bradycardia (choice B) is not typically associated with a hemolytic transfusion reaction. Chills (choice C) can be seen in febrile non-hemolytic transfusion reactions. Distended neck veins (choice D) are more indicative of fluid overload rather than a hemolytic reaction.

Correct Answer: C

Rationale: The correct answer is C. Levothyroxine is a lifelong medication for clients with hypothyroidism, and it should be taken as prescribed. Choice A is incorrect because levothyroxine should be taken on an empty stomach. Choice B is incorrect because levothyroxine is usually taken in the morning on an empty stomach. Choice D is incorrect because stopping the medication abruptly can have adverse effects on thyroid function.
