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. A nurse working in a pediatric clinic observes bruises on the body of a four-year-old boy. The parents report the boy fell while riding his bike. The bruises are located on his posterior chest wall and gluteal region. What should the nurse do?

• A. Suggest a script for counseling the family to the doctor on duty.
• B. Recommend a warm bath for the boy to decrease healing time.
• C. Notify the case manager in the clinic about possible child abuse concerns.
• D. Recommend ROM exercises to the patient's spine to decrease healing time.

Correct answer: C

Rationale: In this scenario, the nurse is observing bruises on a child's body that are located in areas not commonly associated with accidental injuries. Given the concerning nature of the bruising pattern and the inconsistent history provided by the parents, the nurse should suspect possible child abuse and take appropriate action by notifying the case manager in the clinic. The safety and well-being of the child should always be the top priority. Counseling for the family, warm baths, or recommending range of motion (ROM) exercises are not appropriate actions in this situation and may not address the underlying issue of potential child abuse.

3. A client with a history of peptic ulcer disease arrives in the emergency department complaining of weakness and states that he vomited 'a lot of dark coffee-looking stomach contents.' The client is cool and moist to the touch. BP 90/50, HR 110, RR 20, T 98. Of the following physician orders, which will the nurse perform first?

• A. Initiate oxygen at 2 liters/nasal cannula.
• B. Start an IV of NS at 150 ml/hr
• C. Insert NG tube to low suction
• D. Attach the client to the ECG monitor

Correct answer: A

Rationale: The correct answer is to initiate oxygen at 2 liters/nasal cannula. The client is presenting signs of shock with hypotension, tachycardia, and cool, moist skin, which indicate poor tissue perfusion. Oxygen should be administered first to improve tissue oxygenation. While all interventions are important, oxygenation takes priority in the ABCs of emergency care. Starting an IV of NS, inserting an NG tube, and attaching the client to the ECG monitor are necessary interventions but should follow the priority of oxygen administration in this scenario.

4. Which physiologic mechanism best describes the function of the sodium-potassium pump?

• A. active transport
• B. diffusion
• C. filtration
• D. osmosis

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.

5. Which of the following medications is not classified as a neuromuscular blocker?

• A. Anectine
• B. Pavulon
• C. Pitressin
• D. Mivacron

Correct answer: C

Rationale: The correct answer is Pitressin. Pitressin is a hormone replacement medication and is not classified as a neuromuscular blocker. Choices A, B, and D (Anectine, Pavulon, Mivacron) are neuromuscular blockers used during anesthesia to induce muscle relaxation for various procedures. Anectine is also known as succinylcholine, Pavulon is rocuronium, and Mivacron is mivacurium. These medications act on the neuromuscular junction to block the transmission of nerve impulses, leading to muscle relaxation.
