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. When should Montelukast be taken?
- A. At least two hours before exercise
- B. Daily in the evening
- C. Two hours before exercise or daily in the evening
- D. None of the above
Correct answer: B
Rationale: Montelukast should be taken daily in the evening to effectively manage asthma symptoms. Taking it at the same time each day helps maintain a consistent level of the medication in the body, providing optimal control over asthma symptoms and inflammation. Choice A is incorrect because Montelukast should not be taken specifically before exercise, but rather daily. Choice C is incorrect because although taking Montelukast two hours before exercise is not necessary, taking it daily in the evening is essential for its effectiveness. Choice D is incorrect as Montelukast should be taken daily to manage asthma.
3. Which of the following conditions is not typically treated with Hydrochlorothiazide?
- A. CHF
- B. HTN
- C. Nephritis
- D. Hypercalciuria
Correct answer: C
Rationale: Nephritis is not commonly treated with Hydrochlorothiazide. Hydrochlorothiazide is primarily used for managing hypertension (HTN) and congestive heart failure (CHF) by reducing blood pressure and fluid retention. It is not a standard treatment for nephritis, which involves inflammation of the kidneys. Hypercalciuria, characterized by excessive calcium excretion in the urine, is not typically treated with Hydrochlorothiazide either.
4. Which of the following is the antidote for lead poisoning?
- A. Naloxone
- B. Nitrite
- C. CaEDTA
- D. Dialysis
Correct answer: C
Rationale: Calcium disodium ethylenediaminetetraacetic acid (CaEDTA) is the antidote for lead poisoning. CaEDTA works by chelating lead, forming a complex that is then excreted in the urine. It is used in chelation therapy to treat lead poisoning by reducing lead levels in the body.
5. During an admission assessment for a client with severe Aspirin toxicity, which finding should the nurse expect?
- A. Body temperature 35°C (95°F)
- B. Lung crackles
- C. Cool, dry skin
- D. Respiratory depression
Correct answer: D
Rationale: In severe Aspirin toxicity, respiratory depression is an anticipated finding due to the development of respiratory acidosis. Aspirin toxicity can lead to metabolic acidosis, causing the individual to hyperventilate initially to compensate. However, as the condition progresses, respiratory depression can occur, resulting in impaired gas exchange and respiratory acidosis.
