1. For which patient diagnosis would a prescription for nifedipine be least appropriate?

• A. Angina Pectoris
• B. Essential HTN
• C. Atrial Fibrillation
• D. Vasospastic Angina

Correct answer: C

Rationale: Nifedipine primarily acts as a calcium channel blocker, exerting its effects on vascular smooth muscle. It is not effective for treating dysrhythmias like Atrial Fibrillation, which involve abnormalities in the heart's electrical system. Nifedipine is commonly prescribed for conditions such as angina pectoris, essential hypertension, and vasospastic angina due to its vasodilatory and anti-anginal properties. Choices A, B, and D are more appropriate as nifedipine can help in managing angina pectoris, hypertension, and vasospastic angina by reducing myocardial oxygen demand and dilating coronary arteries.

2. Why is the specific gravity for infants lower than for older children?

• A. Infants have a greater body surface area.
• B. Infants have a higher basal metabolic rate.
• C. Infants have a greater percentage of body weight that is water.
• D. Infants' kidneys are less able to concentrate urine.

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

3. A child with suspected bacterial meningitis is under the care of a nurse. Which action should the nurse prioritize?

• A. Administer antibiotics as prescribed.
• B. Maintain the child on NPO status.
• C. Monitor the child's intake and output.
• D. Implement seizure precautions.

Correct answer: D

Rationale: The priority action for a child with suspected bacterial meningitis is to implement seizure precautions. Meningitis can lead to increased intracranial pressure, which may trigger seizures. By implementing seizure precautions, such as padding the side rails of the bed and ensuring a clear environment, the nurse aims to prevent injury during a potential seizure episode, prioritizing the child's safety. Administering antibiotics as prescribed is essential in treating bacterial meningitis, but seizure precautions take precedence due to the immediate risk of injury. Maintaining NPO status and monitoring intake and output are important aspects of care but are not the priority when considering the risk of seizures.

4. The nurse is teaching a patient with cancer about a new prescription for a fentanyl patch, 25mcg/hr. for chronic back pain. Which statement is the most appropriate to include in the teaching plan.

• A. You will need to change this patch every day, regardless of your pain level.
• B. This type of pain medication is not as likely to cause breathing problems.
• C. With the first patch, it will take about 24hrs before you feel the full effects.
• D. Use your heating pad for the back pain. It will also improve the patch�s effectiveness.

Correct answer: C

Rationale: Full analgesic effects can take up to 24 hours to develop with fentanyl patches. Most patches are changed every 72 hours. Has the same adverse effects as other opioids, including respiratory depression. Should avoid exposing the patch to external heat sources, because this may increase toxicity.

5. A child with nephrotic syndrome has not experienced diuresis after a month on corticosteroids. What protocol can the nurse encourage to induce diuresis?

• A. Ibuprofen, an anti-inflammatory agent
• B. Furosemide (Lasix), a diuretic
• C. Ciprofloxacin (Cipro), an antibiotic
• D. Cyclophosphamide (Cytoxan), an immunosuppressant

Correct answer: B

Rationale: To induce diuresis in a child with nephrotic syndrome who has not responded to corticosteroids, a diuretic like Furosemide (Lasix) is appropriate. Furosemide helps increase urine production and reduce fluid retention. Ibuprofen is an anti-inflammatory agent and does not directly induce diuresis. Ciprofloxacin is an antibiotic and is not used to promote diuresis. Cyclophosphamide is an immunosuppressant, not an antisuppressant, and is not typically used to induce diuresis in nephrotic syndrome.
