Nursing Elites

1. The nurse is caring for a client with hyperemesis gravidarum. What is the most likely electrolyte imbalance?

• A. Hypocalcemia
• B. Hypomagnesemia
• C. Hyponatremia
• D. Hypokalemia

Correct answer: D

Rationale: In hyperemesis gravidarum, where the client experiences severe nausea and vomiting, the most likely electrolyte imbalance is hypokalemia. Potassium is abundant in the stomach, and excessive vomiting leads to potassium loss. Hypocalcemia (Choice A) is not typically associated with hyperemesis gravidarum. Hypomagnesemia (Choice B) and Hyponatremia (Choice C) are less likely to occur compared to hypokalemia in this condition.

2. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

• A. metoclopramide (Reglan)
• B. ondansetron (Zofran)
• C. hydroxyzine (Vistaril)
• D. prochlorperazine (Compazine)

Correct answer: B

Rationale: Zofran is a serotonin antagonist that can be used to relieve nausea and vomiting. Ondansetron (Zofran) works by blocking serotonin receptors in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This action helps reduce nausea and vomiting. Metoclopramide (Reglan) works as a dopamine antagonist and also has prokinetic effects, making it effective for different conditions. Hydroxyzine (Vistaril) is an antihistamine with antiemetic properties, but it does not act as a serotonin antagonist. Prochlorperazine (Compazine) is a dopamine antagonist that is also used to treat nausea and vomiting, but not as a serotonin antagonist like ondansetron.

3. A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?

• A. COPD clients are stimulated to breathe by hypoxia.
• B. COPD clients depend on a low carbon dioxide level.
• C. COPD clients tend to retain hydrogen ions if they are given high doses of oxygen.
• D. COPD clients thrive on a high oxygen level.

Correct answer: A

Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.

4. A client admitted with an episode of bleeding esophageal varices is receiving propranolol (Inderal LA). The nurse knows to monitor for?

• A. Hypertension
• B. Hyperkalemia
• C. Bradycardia
• D. Arthralgia

Correct answer: C

Rationale: The correct answer is 'Bradycardia.' Propranolol is a beta-blocking agent used to decrease the heart rate. In the case of bleeding esophageal varices, propranolol is given to reduce the risk of bleeding by keeping the heart rate around 55 beats per minute. Monitoring for bradycardia is essential as the medication's intended effect is to lower the heart rate. Choices A, B, and D are incorrect because propranolol would not typically cause hypertension, hyperkalemia, or arthralgia.

5. The client has just returned from electroconvulsive therapy (ECT) and is very drowsy. What is the position of choice until the client regains full consciousness?

• A. Supine
• B. Fowlers
• C. Lateral
• D. High Fowlers

Correct answer: C

Rationale: The correct answer is 'Lateral.' When a client is very drowsy or sedated, placing them in the lateral position is important to maintain an open airway and allow for drainage of secretions. This position helps prevent airway obstruction and aspiration. Choice A, 'Supine,' is lying flat on the back and may not be ideal for a drowsy client due to the risk of airway compromise. Choice B, 'Fowlers,' is a semi-sitting position that is beneficial for clients with respiratory distress, but it may not be the best choice for a very drowsy individual. Choice D, 'High Fowlers,' is a more upright sitting position, which again may not be suitable for a drowsy client as it does not facilitate airway patency as effectively as the lateral position.
