1. What is the approximate duration of action for intermediate-acting insulins like NPH?

• A. 6-8 hours.
• B. 10-14 hours.
• C. 16-20 hours.
• D. 24-28 hours.

Correct answer: C

Rationale: The correct answer is C: '16-20 hours.' Intermediate-acting insulins like NPH typically have a duration of action of approximately 16-20 hours. This prolonged action makes them effective in managing blood glucose levels over an extended period. Choices A, B, and D are incorrect because they do not align with the typical duration of action for intermediate-acting insulins. Choice A (6-8 hours) is too short, choice B (10-14 hours) is also shorter than the typical duration, and choice D (24-28 hours) is too long for intermediate-acting insulins like NPH.

2. A female client with a history of pheochromocytoma is admitted to the hospital in an acute hypertensive crisis. To reverse the hypertensive crisis caused by pheochromocytoma, nurse Lyka expects to administer:

• A. Phentolamine (Regitine)
• B. Methyldopa (Aldomet)
• C. Mannitol (Osmitrol)
• D. Felodipine (Plendil)

Correct answer: A

Rationale: In a hypertensive crisis due to pheochromocytoma, the appropriate medication to administer is Phentolamine (Regitine), an alpha-adrenergic blocker. Phentolamine acts quickly to block the effects of excess catecholamines that are released in pheochromocytoma, helping to rapidly lower blood pressure. Methyldopa (Aldomet) is an alpha-2 adrenergic agonist used for chronic hypertension, not for acute crises like pheochromocytoma. Mannitol (Osmitrol) is an osmotic diuretic used to reduce intracranial pressure and treat cerebral edema, not indicated for hypertensive crises. Felodipine (Plendil) is a calcium channel blocker used for chronic management of hypertension, not for acute hypertensive crises like those seen in pheochromocytoma.

3. The healthcare provider is caring for a client with Cushing's syndrome. Which of the following nursing interventions is appropriate?

• A. Monitor blood glucose levels
• B. Restrict fluid intake
• C. Administer potassium supplements
• D. Encourage a high-protein diet

Correct answer: A

Rationale: Clients with Cushing's syndrome are at risk for hyperglycemia due to the effects of cortisol on glucose metabolism. Monitoring blood glucose levels is crucial to detect and manage hyperglycemia promptly. Restricting fluid intake (choice B) is not necessary unless specifically indicated for another condition, as clients with Cushing's syndrome are prone to fluid imbalances. Administering potassium supplements (choice C) is not appropriate as clients with Cushing's syndrome often have elevated potassium levels due to the effects of cortisol. Encouraging a high-protein diet (choice D) is not recommended as clients with Cushing's syndrome should focus on a balanced diet to manage their condition effectively.

4. Which of the following statements is true regarding ethical principles and laws?

• A. The government enforces ethics.
• B. Laws establish standards that aid in decision-making.
• C. Ethics are highly specific.
• D. Ethical principles can serve as the foundation for laws.

Correct answer: D

Rationale: The correct answer is D. Ethical principles can influence the creation of laws but are not equivalent to laws themselves. Laws are established by governing bodies to provide a framework for society, whereas ethical principles guide individuals' moral conduct. Choice A is incorrect because governments enforce laws, not ethics. Choice B is incorrect as laws set legal standards rather than ethical ones. Choice C is incorrect because ethics are principles that guide behavior but are not necessarily highly specific.

5. A male client with primary diabetes insipidus is ready for discharge on desmopressin (DDAVP). Which instruction should nurse Lina provide?

• A. Administer desmopressin while the suspension is cold.
• B. Your condition isn't chronic, so you won't need to wear a medical identification bracelet.
• C. You may not be able to use desmopressin nasally if you have nasal discharge or blockage.
• D. You won't need to monitor your fluid intake and output after you start taking desmopressin.

Correct answer: C

Rationale: The correct instruction is choice C: 'You may not be able to use desmopressin nasally if you have nasal discharge or blockage.' Nasal congestion or blockage can interfere with the absorption of nasally administered desmopressin. Choices A, B, and D are incorrect. Choice A is unnecessary as the temperature of the suspension does not impact desmopressin administration. Choice B is incorrect as wearing a medical identification bracelet is essential for individuals with diabetes insipidus to alert healthcare providers in case of emergencies. Choice D is incorrect as monitoring fluid intake and output is crucial when taking desmopressin to ensure proper hydration and medication effectiveness.
