1. What is the expected pharmacological action of propranolol?

• A. Block stimulation of beta1 receptors
• B. Alter water and electrolyte transport in the large intestine
• C. Block stimulation of beta2 receptors
• D. Both A and C are correct

Correct answer: D

Rationale: Propranolol exerts its pharmacological action by blocking stimulation of both beta1 and beta2 receptors. By doing so, it leads to decreased heart rate and blood pressure. Therefore, both options A and C are correct as propranolol affects both types of beta receptors. Choice B is incorrect as propranolol does not alter water and electrolyte transport in the large intestine.

2. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?

• A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
• B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
• C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
• D. Draw a peak level at 0900 and a trough level at 2100.

Correct answer: C

Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.

3. A healthcare professional is preparing to administer clindamycin 200 mg by intermittent IV bolus. The amount available is clindamycin injection 200 mg in 100 mL 0.9% sodium chloride (0.9% NaCl) to infuse over 30 min. The healthcare professional should set the IV pump to deliver how many mL/hr?

• A. 200 mL/hr
• B. 150 mL/hr
• C. 100 mL/hr
• D. 250 mL/hr

Correct answer: A

Rationale: To calculate the flow rate in mL/hr: (Volume in mL / Time in hours) = Flow rate in mL/hr. In this case, (100 mL / 0.5 hr) = 200 mL/hr. The correct calculation is: 100 mL (volume) / 0.5 hr (time) = 200 mL/hr. Therefore, the correct answer is 200 mL/hr. Choice B (150 mL/hr), C (100 mL/hr), and D (250 mL/hr) are incorrect as they do not match the calculated flow rate needed for the administration of clindamycin.

4. When reviewing a client's health record, a healthcare professional notes that the client is experiencing episodes of hypokalemia. Which of the following medications should be identified as a cause of the client's hypokalemia?

• A. Captopril
• B. Lisinopril
• C. Furosemide
• D. Spironolactone

Correct answer: C

Rationale: Furosemide, a loop diuretic, can lead to hypokalemia by increasing the excretion of potassium in the urine. This potassium loss can result in lower-than-normal levels of potassium in the body, leading to hypokalemia.

5. When discussing immunizations, which vaccine series is typically completed before a child's first birthday?

• A. Pneumococcal conjugate vaccine
• B. Meningococcal conjugate vaccine
• C. Varicella vaccine
• D. Rotavirus vaccine

Correct answer: D

Rationale: The correct answer is D, Rotavirus vaccine. The rotavirus vaccine series is usually completed before a child's first birthday. It is given to infants in a series of doses starting at 2 months of age and must be completed by 8 months of age. This vaccine helps protect against severe diarrhea and vomiting caused by rotavirus infection, which is common in infants and young children. Choices A, B, and C are incorrect because the Pneumococcal conjugate vaccine, Meningococcal conjugate vaccine, and Varicella vaccine are not typically completed before a child's first birthday.
