A client with asthma is being taught how to use a peak flow meter by a nurse. Which of the following instructions should the nurse include?

Correct Answer: D

Rationale: The correct instruction is to use the peak flow meter after using the rescue inhaler. This ensures accurate monitoring of asthma control during symptoms. Choice A is incorrect because peak flow measurements should be done before taking medications. Choice B is incorrect as the client should blow into the meter quickly and forcefully to get an accurate reading. Choice C is also incorrect as peak flow should be measured regularly, not just when feeling short of breath.

Correct Answer: A

Rationale: Muscle weakness is a characteristic finding in hyperkalemia. High levels of potassium can affect the normal function of muscles, leading to weakness. Nausea and increased thirst are not typically associated with hyperkalemia. Restlessness is more commonly seen in conditions such as hypoxia or anxiety, not specifically in hyperkalemia.

Correct Answer: A

Rationale: The signs of hypoglycemia include shakiness, confusion, hunger, dizziness, and lightheadedness. However, the classic and most common early sign is shakiness or tremors. When a patient is experiencing hypoglycemia, a healthcare provider should respond promptly by administering glucose to raise the blood sugar levels. Choice A is correct as it directly addresses one of the primary signs of hypoglycemia. Choices B, C, and D are incorrect because while confusion, irritability, hunger, dizziness, and lightheadedness can also be signs of hypoglycemia, shakiness or tremors are the classic and most common early symptoms that healthcare providers should be particularly vigilant for.

Correct Answer: A

Rationale: The correct nursing priority for a patient experiencing an asthma exacerbation is to administer a bronchodilator. Bronchodilators help in relieving bronchoconstriction and improving breathing. While encouraging deep breathing, providing oxygen therapy, and monitoring oxygen saturation are essential aspects of managing asthma exacerbation, the priority is to administer a bronchodilator to address the acute bronchoconstriction.

Correct Answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with chest pain because it helps relieve chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Assessing pain level, monitoring vital signs, and providing oxygen therapy are important interventions as well, but administering nitroglycerin takes precedence in addressing the immediate symptom of chest pain and potential cardiac ischemia.
