Nursing Elites

1. In alcoholics with anemia:

• A. Pernicious anemia is more common than folic acid deficiency.
• B. Iron deficiency and folic acid deficiency can coexist.
• C. The alcohol interferes with iron absorption.
• D. Oral vitamin replacement is contraindicated.

Correct answer: B

Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.

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. The client is undergoing progressive ambulation on the third day after a myocardial infarction. Which clinical manifestation would indicate that the client should not be advanced to the next level?

• A. Facial flushing
• B. A complaint of chest heaviness
• C. Heart rate increase of 10 beats/min
• D. Systolic blood pressure increase of 10 mm Hg

Correct answer: B

Rationale: The correct answer is a complaint of chest heaviness. Onset of chest pain indicates myocardial ischemia, which can be life-threatening. Chest pain in a client post-myocardial infarction should be promptly evaluated, and the activity level should not be advanced. Choices A, C, and D are not the best options because facial flushing, a heart rate increase of 10 beats/min, and a systolic blood pressure increase of 10 mm Hg are not typical indicators of myocardial ischemia or necessarily contraindications for advancing activity levels in this context.

4. 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.

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.
