A nurse caring for a group of clients reviews the electrolyte laboratory results and notes a potassium level of 5.5 mEq/L on one client's laboratory report. The nurse understands that which client is at highest risk for the development of a potassium value at this level?
- A. The client with colitis
- B. The client with Cushing's syndrome
- C. The client who has been overusing laxatives
- D. The client who has sustained a traumatic burn
Correct Answer: D
Rationale: Clients who have sustained traumatic burns are at a higher risk of developing hyperkalemia due to cell lysis. When cells are damaged in a traumatic burn, potassium can leak out from the intracellular space into the bloodstream, leading to elevated serum potassium levels. Colitis, Cushing's syndrome, and overuse of laxatives are not typically associated with the same degree of cell damage or potassium shifts seen in traumatic burns, making them less likely to result in such high potassium levels.

An RN enters a patient's room to place an indwelling urinary catheter, as ordered by the healthcare professional. The client is alert and oriented and tells the RN he wants to leave the hospital now and not receive further treatment. Which of the following actions by the RN would be considered false imprisonment?
- A. The RN tells the client he is not allowed to leave until the physician has released him.
- B. The RN asks the client why he wishes to leave.
- C. The RN asks the client to explain what he understands about his medical diagnosis.
- D. The RN asks the client to sign an against medical advice discharge form.
Correct Answer: A
Rationale: False imprisonment occurs when a person is prevented from leaving against their will. By telling the patient they are not allowed to leave, the RN is restricting the patient's freedom unlawfully. Choice B is focused on understanding the patient's reasons for leaving and does not involve restricting the patient's freedom. Choice C aims to assess the patient's understanding of their medical condition, which is unrelated to false imprisonment. Choice D involves obtaining consent for leaving against medical advice, which is a legal and ethical process and not false imprisonment.
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.
After taking glipizide (Glucotrol) for 9 months, a male client experiences secondary failure. What would the nurse expect the physician to do?
- A. Initiate insulin therapy.
- B. Switch the client to a different oral antidiabetic agent.
- C. Prescribe an additional oral antidiabetic agent.
- D. Restrict carbohydrate intake to less than 30% of the total caloric intake.
Correct Answer: A
Rationale: When a client experiences secondary failure to an oral antidiabetic agent like glipizide, the next step is often to initiate insulin therapy. This is because secondary failure indicates that the current oral antidiabetic medication is no longer effective in managing blood glucose levels, and insulin therapy may be required to adequately control blood sugar. Switching to a different oral antidiabetic agent may not be effective if there is already resistance to the current agent. Adding another oral antidiabetic agent may not address the underlying issue of secondary failure. Restricting carbohydrate intake is important for diabetes management but is not the primary intervention indicated in this scenario of secondary failure to glipizide.
Albert refuses his bedtime snack. This should alert the healthcare provider to assess for:
- A. Elevated serum bicarbonate and decreased blood pH.
- B. Signs of hypoglycemia earlier than expected.
- C. Symptoms of hyperglycemia due to NPH insulin peak time.
- D. Presence of sugar in the urine.
Correct Answer: B
Rationale: When a patient like Albert refuses his bedtime snack, it can lead to hypoglycemia, especially if they are on medication such as insulin. Hypoglycemia can occur earlier than expected due to the lack of carbohydrate intake before bedtime. This situation warrants the healthcare provider to monitor for signs and symptoms of hypoglycemia. Choice A is incorrect because the given scenario is more indicative of hypoglycemia than metabolic alkalosis. Choice C is incorrect as NPH insulin peak time is not directly related to skipping a bedtime snack. Choice D is incorrect as sugar in the urine typically indicates hyperglycemia, not hypoglycemia.
A client with type 1 DM is admitted to the hospital with diabetic ketoacidosis (DKA). The nurse should prioritize which action?
- A. Administering intravenous fluids.
- B. Administering oral glucose.
- C. Administering a fever-reducing medication.
- D. Administering oxygen therapy.
Correct Answer: A
Rationale: Administering intravenous fluids is the priority in treating DKA for several reasons. DKA is characterized by severe dehydration and electrolyte imbalances due to hyperglycemia. IV fluids help to correct dehydration, restore electrolyte balance, and decrease blood glucose levels. Administering oral glucose (Choice B) would be contraindicated in DKA as the primary issue is high blood glucose levels. Administering a fever-reducing medication (Choice C) is not the priority in managing DKA. Administering oxygen therapy (Choice D) may be necessary in some cases, but correcting dehydration and electrolyte imbalances take precedence in the management of DKA.
