Correct Answer: A

Rationale: The correct answer is A: Check for signs of infection. This is crucial because chemotherapy weakens the immune system, increasing the risk of infections. Signs of infection such as fever, chills, sore throat, and cough should be closely monitored to prevent serious complications. Monitoring weight (B) and nutrition (C) are important but not as critical as detecting infections promptly. Checking for skin changes (D) is also important, but it is secondary to identifying and managing infections due to the immediate threat they pose to the client's health.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. This is the nurse's first action for a client with a suspected MI because nitroglycerin helps dilate blood vessels, improving blood flow to the heart. This can help reduce chest pain and prevent further damage to the heart muscle. Administering nitroglycerin promptly is crucial in managing an MI. Monitoring cardiac rhythm (B) and assessing the ECG (C) are important steps, but administering nitroglycerin takes precedence in addressing the client's immediate symptoms. Assisting with positioning (D) is not as urgent or directly related to managing an MI compared to administering nitroglycerin.

Correct Answer: C

Rationale: The correct quadrant for tenderness in suspected appendicitis is the lower right quadrant (Choice C). This is because the appendix is located in the lower right abdomen. Appendicitis typically presents with pain starting around the navel and then localizing to the lower right quadrant. The other choices, upper right (Choice A), upper left (Choice B), and lower left (Choice D) are incorrect as they do not correspond to the typical location of the appendix. Upper right quadrant is where the liver and gallbladder are situated, upper left quadrant contains the stomach and spleen, and lower left quadrant has the colon and left ovary/testis.

Correct Answer: A

Rationale: The priority nursing intervention for a client with asthma experiencing wheezing is to administer oxygen. Wheezing indicates airway constriction and decreased oxygenation, making oxygen crucial for adequate tissue perfusion. Administering oxygen helps improve oxygen levels, alleviate respiratory distress, and prevent hypoxemia. Applying a bronchodilator (Choice B) may be beneficial after oxygen is administered. Applying a cold compress (Choice C) is not indicated for asthma exacerbations, and encouraging deep breathing (Choice D) may worsen respiratory distress in a client with wheezing. In summary, administering oxygen is the priority intervention to address the immediate respiratory needs of the client with asthma and wheezing.

Correct Answer: A

Rationale: The correct answer is A because avoiding environmental allergens and cold air can help prevent asthma attacks. This shows the patient understands the importance of managing triggers. Choice B is incorrect because over-the-counter medications may not be sufficient for asthma management. Choice C is incorrect because smoking can worsen asthma symptoms. Choice D is incorrect because using the inhaler only when feeling short of breath is not a proactive approach to managing asthma triggers.
