Nursing Elites

1. What physiologic role does magnesium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

2. A Hazard Analysis and Critical Control Points (HACCP) program would address which element of food service?

• A. cleaning and disinfecting of utensils
• B. developing healthy menus
• C. controlling patient calorie intake
• D. prescribing diets for patients with swallowing problems

Correct answer: A

Rationale: The correct answer is A. Hazard Analysis and Critical Control Points (HACCP) programs are designed to ensure food safety by identifying and controlling potential hazards. This includes addressing the cleaning and disinfecting of utensils to prevent contamination and maintain safe food handling practices. Choices B, C, and D are incorrect because HACCP primarily focuses on preventing food safety hazards rather than developing menus, controlling calorie intake, or prescribing diets for specific medical conditions.

3. Mrs. Seva also tells the nurse that she is often constipated. Because she is aging, what physical changes predispose her to constipation?

• A. inhibition of the parasympathetic reflex
• B. weakness of sphincter muscles of anus
• C. loss of tone of the smooth muscles of the colon
• D. decreased ability to absorb fluids in the lower intestines

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. A nurse is reviewing the medication administration record for a client who is 2 days postoperative following abdominal surgery. The nurse should recognize that which of the following medications places the client at risk for wound dehiscence?

• A. Omeprazole
• B. Zolmitriptan
• C. Prednisone
• D. Verapamil

Correct answer: C

Rationale: Corrected Rationale: Prednisone is a corticosteroid that can impair wound healing and increase the risk of wound dehiscence. Omeprazole (Choice A) is a proton pump inhibitor used to reduce stomach acid production and does not directly impact wound healing. Zolmitriptan (Choice B) is a medication used to treat migraines and does not affect wound healing. Verapamil (Choice D) is a calcium channel blocker used to treat high blood pressure and certain heart conditions, and it does not pose a significant risk for wound dehiscence.

5. A nurse is discussing denture care with the partner of a client who is unable to perform oral hygiene. Which of the following should be included in the discussion?

• A. Floss dentures as part of daily cleaning.
• B. Wipe dentures before storing them in a dry container at night.
• C. Wrap gloved fingers with gauze to remove dentures.
• D. Use a washcloth to clean the denture surfaces.

Correct answer: C

Rationale: The correct answer is C: 'Wrap gloved fingers with gauze to remove dentures.' This method provides a safe and effective way to remove dentures without causing damage. Choice A is incorrect because flossing dentures is not recommended. Choice B is incorrect as it suggests wiping dentures and storing them dry, which is not the best practice. Choice D is incorrect because using a washcloth may not effectively clean all denture surfaces.
