Correct Answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.

Correct Answer: B

Rationale: The correct answer is to wear gloves when applying the transdermal nicotine patch to prevent the nurse from absorbing nicotine through the skin. Choice A is incorrect because shaving hairy areas of skin is not necessary for applying a transdermal patch. Choice C is incorrect as transdermal patches should be applied immediately after removal from the protective pouch, not necessarily within 1 hour. Choice D is incorrect because the previous patch should be disposed of properly following institutional guidelines, not placed in a tissue.

Correct Answer: D

Rationale: The correct answer is D: 'I should report any chest pain during the test.' This statement indicates an understanding of the teaching because reporting chest pain during an exercise stress test is crucial as it may signify cardiac distress. Choices A, B, and C are incorrect. Eating a large meal 2 hours before the test is not recommended as it may affect the results. Avoiding drinking water before the test is also not advisable as staying hydrated is important. Stopping blood pressure medication without medical advice can be dangerous, especially before a stress test.

Correct Answer: D

Rationale: The correct answer is D. An HbA1c level less than 7% indicates good long-term glucose control for clients with diabetes. This goal reflects optimal glycemic control and reduces the risk of long-term complications. Choices A, B, and C are incorrect because they do not represent appropriate goals for managing type 1 diabetes in an adolescent. An HbA1c level greater than 8% (choice A) signifies poor glucose control, while a blood glucose level greater than 200 mg/dL at bedtime (choice B) and a blood glucose level less than 60 mg/dL before breakfast (choice C) are not within the target ranges for safe and effective diabetes management.

Correct Answer: B

Rationale: Irritability is indeed an early sign that a tracheostomy client may require suctioning. When a tracheostomy client becomes irritable, it can indicate that there is a need for suctioning to clear the airway. Bradycardia (choice A) refers to a slow heart rate and is not typically a direct indication for suctioning. Hypotension (choice C) indicates low blood pressure and is not specifically related to the need for suctioning. Decreased respiratory rate (choice D) can be a sign of respiratory distress, but irritability is a more direct and early indication of the need for suctioning in a tracheostomy client.
