1. Which of the following qualifications is not required for a Nurse Supervisor at the provincial level?
- A. BSN, RN
- B. at least 3 years experience
- C. Master's in public health
- D. at least 5 years experience in public health
Correct answer: B
Rationale: The correct answer is B because the qualifications for a Nurse Supervisor at the provincial level include a BSN, RN, and a Master's in public health, along with a minimum of 5 years of experience in public health. Choice B, which states 'at least 3 years experience,' is incorrect as the requirement is for at least 5 years of experience in public health. Choices A, C, and D are necessary qualifications for a Nurse Supervisor at the provincial level based on the provided information.
2. A child with a diagnosis of sickle cell anemia is admitted to the hospital with a vaso-occlusive crisis. What is the most important nursing intervention?
- A. Administering oxygen
- B. Administering pain medication
- C. Monitoring fluid intake
- D. Encouraging physical activity
Correct answer: B
Rationale: During a vaso-occlusive crisis in sickle cell anemia, the priority nursing intervention is administering pain medication to alleviate the severe pain associated with the crisis. While administering oxygen can help improve oxygenation, pain relief is crucial in managing the crisis. Monitoring fluid intake is important in sickle cell anemia but is not the most immediate intervention during a vaso-occlusive crisis. Encouraging physical activity is contraindicated during a vaso-occlusive crisis as it can exacerbate pain and complications.
3. What is the most important information the nurse should teach a diabetic client about foot care?
- A. Inspect feet daily
- B. Wear cotton socks
- C. Use lukewarm water to wash feet
- D. Cut nails straight across
Correct answer: A
Rationale: The correct answer is to inspect feet daily. For diabetic clients, daily foot inspection is crucial in preventing complications like infections and ulcers. By checking their feet regularly, clients can identify any issues early and seek appropriate medical care. The other choices are important aspects of foot care for diabetic clients but not as critical as daily foot inspections. Wearing cotton socks helps in moisture control, using lukewarm water to wash feet helps prevent skin damage, and cutting nails straight across prevents ingrown nails. However, daily foot inspection is the most vital as it allows for early detection of any potential problems, which is key in diabetic foot care.
4. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?
- A. Increases heart rate
- B. Lowers blood pressure
- C. Dilates coronary arteries
- D. Reduces myocardial oxygen demand
Correct answer: C
Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.
5. A client is being taught about the use of an incentive spirometer. Which statement by the client indicates effective teaching?
- A. I will use the spirometer every hour while awake.
- B. I will blow into the spirometer as hard as I can.
- C. I should feel dizzy when using the spirometer.
- D. I will only use the spirometer if I feel short of breath.
Correct answer: A
Rationale: The correct answer is A because using the spirometer every hour while awake is an effective way to prevent respiratory complications. This frequency helps in maintaining lung function and preventing atelectasis. Choice B is incorrect because blowing too hard into the spirometer can lead to hyperventilation and dizziness, making choice C also incorrect. Choice D is wrong as waiting to use the spirometer only when feeling short of breath may not provide optimal lung expansion and can lead to respiratory issues.
