Nursing Elites

1. Which client is at risk for hypomagnesemia?

• A. Client with a history of heart disease
• B. Client taking magnesium-based antacids
• C. Client with a parathyroid disorder
• D. Client admitted with alcohol abuse

Correct answer: D

Rationale: The correct answer is the client admitted with alcohol abuse. Alcoholics tend to have poor nutrition due to decreased food intake, which is a common source of magnesium. Additionally, alcohol suppresses the release of ADH, leading to diuresis and magnesium loss. Choice A is incorrect because a history of heart disease does not directly increase the risk of hypomagnesemia. Choice B is incorrect as taking magnesium-based antacids would not put the client at risk for hypomagnesemia; in fact, it would help prevent it. Choice C is also incorrect as a parathyroid disorder is not typically associated with an increased risk of hypomagnesemia.

2. In the treatment of symptomatic bradycardia, which medication is most commonly recognized?

• A. Questran
• B. Digitalis
• C. Nitroglycerin
• D. Atropine

Correct answer: D

Rationale: Atropine is the medication most commonly recognized for the treatment of symptomatic bradycardia because it increases the rate of conduction in the AV node, helping to alleviate bradycardia. Questran is a medication used to lower cholesterol levels and is not indicated for bradycardia. Digitalis, such as Digoxin, is used for heart failure and atrial fibrillation but not typically for bradycardia. Nitroglycerin is primarily used for angina and not bradycardia.

3. Melissa Smith came to the Emergency Department in the last week before her estimated date of confinement complaining of headaches, blurred vision, and vomiting. Suspecting PIH, the nurse should best respond to Melissa's complaints with which of the following statements?

• A. "The physician will probably want to admit you for observation."?
• B. "The physician will probably order bedrest at home."?
• C. "These are really dangerous signs."?
• D. "The physician will probably prescribe some medicine for you."?

Correct answer: B

Rationale: Pregnancy-induced hypertension (PIH) is a hypertensive disorder of pregnancy that can present after 20 weeks gestation. It is characterized by symptoms like edema, hypertension, and proteinuria, which can progress to conditions like pre-eclampsia and eclampsia. The best approach for a client with advanced PIH is rest, and home provides the most suitable environment for it. Hospitalization is not typically necessary for PIH unless there are severe complications. Medication alone is not the primary intervention for PIH; management often involves monitoring, rest, and close medical supervision. Therefore, advising bedrest at home is the most appropriate response to help manage PIH symptoms and prevent further complications, such as pre-eclampsia or eclampsia. The other options, like hospitalization for observation, emphasizing the danger of the signs without providing guidance, or assuming medication as the primary solution, are not in line with the standard management approach for PIH.

4. The client asked about the role of leptin in the body. Which response should the nurse provide?

• A. It increases food intake in clients, thereby promoting obesity.
• B. It assists in the regulation of steroids.
• C. It increases the total fat mass of people who are obese.
• D. It might decrease the total fat mass in the bodies of people who are obese.

Correct answer: D

Rationale: Leptin is a protein hormone expressed in fat cells that regulates fat cell percentage in the body. It is associated with increased energy expenditure and decreased food intake through hypothalamic control. In obese individuals, there may be insensitivity or resistance to leptin's effects. Leptin influences other hormones like insulin and genetic factors related to fat regulation. Therefore, the correct response is that leptin might decrease total fat mass in obese individuals as it is involved in energy balance and fat regulation. Choices A, B, and C are incorrect because leptin does not increase food intake or promote obesity; it does not assist in the regulation of steroids, and it does not increase total fat mass in people who are obese.

5. In a client with asthma who develops respiratory acidosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.
