Nursing Elites

1. Which menu choices for a child diagnosed with renal failure and experiencing hyperkalemia indicate the need for further instruction by the nurse?

• A. Carrots and green, leafy vegetables
• B. Spaghetti and meat sauce with breadsticks
• C. Hamburger on a bun and cherry gelatin
• D. Chips, cold cuts, and canned foods

Correct answer: A

Rationale: Carrots and green, leafy vegetables are high in potassium, which should be avoided in hyperkalemia. Therefore, this choice requires further instruction by the nurse to prevent exacerbating the child's condition.

2.

• A. Take medication on a full stomach
• B. Change positions slowly
• C. The drug may cause the urine to be very dilute
• D. Carbidopa has many adverse effects

Correct answer: B

Rationale: Postural hypotension is common early in treatment, so the patient should be instructed to change positions slowly. Administration with meals should be avoided, if possible, because food delays the absorption of the levodopa component. If the patient is experiencing side effects of nausea and vomiting, administration with food may be considered. The levodopa component may darken urine. Carbidopa has no adverse effects of its own.

3. A newborn diagnosed with an omphalocele defect is admitted to the intensive care nursery. Which nursing action is appropriate based on the current data?

• A. Placing the newborn on a radiant warmer
• B. Placing the newborn in an open crib
• C. Preparing the newborn for phototherapy
• D. Preparing the newborn for bottle-feeding

Correct answer: A

Rationale: Placing the newborn on a radiant warmer is appropriate as it helps maintain the body temperature and prevent hypothermia in a newborn with an omphalocele defect. This is crucial for the infant's well-being and supports their physiological stability.

4. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

5. Which medication is most likely to cause serious respiratory depression as a potential adverse reaction?

• A. Morphine
• B. Pentazocine
• C. Hydrocodone
• D. Nalmefene

Correct answer: A

Rationale: Morphine, as a strong opioid agonist, has the highest likelihood of causing serious respiratory depression due to its potent effects on the central nervous system. While Pentazocine and Hydrocodone can also cause respiratory depression, they are less likely to do so compared to morphine. Nalmefene, an opioid antagonist, is used to reverse respiratory depression caused by opioids rather than causing it.
