1. What type of cells create exocrine secretions?

• A. alpha cells
• B. beta cells
• C. acinar cells
• D. plasma cells

Correct answer: C

Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.

2. Which symptoms is the client who overdosed on barbiturates most likely to exhibit?

• A. Bradypnea and bradycardia
• B. Hyperthermia and drowsiness
• C. Hyperreflexia and slurred speech
• D. Tachycardia and psychosis

Correct answer: A

Rationale: The correct answer is bradypnea and bradycardia. Barbiturates are central nervous system (CNS) depressants, which will slow down the respiratory rate (bradypnea) and heart rate (bradycardia). Choice B, hyperthermia and drowsiness, is incorrect as barbiturate overdose typically does not cause hyperthermia but rather hypothermia. Hyperreflexia and slurred speech (Choice C) are more indicative of stimulant overdoses rather than CNS depressants like barbiturates. Tachycardia and psychosis (Choice D) are also not typically seen in barbiturate overdose, as these drugs tend to depress the CNS rather than cause symptoms of increased heart rate or psychosis.

3. Is head lag expected to be resolved by 4 months of age? Continuing head lag at 6 months of age may indicate?

• A. Dizziness and orthostatic hypotension.
• B. Nausea, vomiting, diarrhea, or constipation, and stomach cramps.
• C. Drowsiness, lethargy, and fatigue.
• D. Neuropathy and tingling in the extremities.

Correct answer: B

Rationale: Head lag is a developmental milestone that should be resolved by 4 months of age. Continuing head lag at 6 months of age may indicate potential developmental delays or muscle weakness. The correct answer, 'Nausea, vomiting, diarrhea, or constipation, and stomach cramps,' reflects symptoms that could be associated with developmental delays or underlying health conditions. Dizziness and orthostatic hypotension (Choice A) are unlikely to be directly related to head lag. Choices C and D present symptoms that are unrelated to the issue of continued head lag at 6 months of age.

4. 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.

5. After a client with an Automated Internal Cardiac Defibrillator (AICD) is successfully defibrillated for Ventricular Fibrillation (VF), what should the nurse do next?

• A. Go to the client to assess for signs and symptoms of decreased cardiac output.
• B. Call the physician to inform them of the VF episode for medication adjustments.
• C. Call the 'on-call' person in the cath lab to re-charge the ICD in case of a recurrence.
• D. Document the incident on the code report form and follow up regularly.

Correct answer: A

Rationale: After a client is successfully defibrillated, the immediate priority is to assess the client for signs and symptoms of decreased cardiac output, such as altered level of consciousness, chest pain, shortness of breath, or hypotension. This assessment is crucial to determine the effectiveness of the defibrillation and the client's current hemodynamic status. Calling the physician for medication adjustments without assessing the client first could delay essential interventions. Contacting the 'on-call' person in the cath lab to re-charge the ICD is not the initial action needed after successful defibrillation. Documenting the incident is important but should not take precedence over assessing the client's immediate condition.
