A nurse is caring for a client who has a potassium level of 3.2 mEq/L (3.5 to 5 mEq/L). Which of the following foods should the nurse recommend as being the best source of potassium?
1⁄2 cup apple juice
½ cup steamed cauliflower
cup boiled white rice
1 cup cantaloupe
The Correct Answer is D
Rationale:
A. ½ cup apple juice: Apple juice contains a relatively low amount of potassium, making it a poor choice for correcting hypokalemia. It typically provides less than 150 mg per half-cup serving.
B. ½ cup steamed cauliflower: Cauliflower is low in potassium compared to other vegetables. While healthy, it does not significantly contribute to raising potassium levels in the body.
C. 1 cup boiled white rice: White rice has minimal potassium content, especially when boiled. It is not effective in increasing potassium and is typically suitable for clients requiring low-potassium diets.
D. 1 cup cantaloupe: Cantaloupe is high in potassium, offering around 400–500 mg per cup. It is among the best fruit sources for replenishing potassium and is appropriate for clients with mild hypokalemia.

Correct Answer is A
Explanation
Rationale:
A. Oxytocin: Oxytocin is the first-line uterotonic used to manage postpartum hemorrhage by stimulating uterine contractions to reduce bleeding. It is safe for use in clients with preeclampsia and does not elevate blood pressure.
B. Methylergonovine: Methylergonovine is contraindicated in clients with preeclampsia or hypertension because it causes vasoconstriction, which can dangerously elevate blood pressure and increase the risk of stroke or seizure.
C. Carboprost: Although carboprost is effective for postpartum hemorrhage, it should be used cautiously in clients with hypertension. It can cause bronchospasm and elevate blood pressure, which may worsen preeclampsia symptoms.
D. Nifedipine: Nifedipine is a calcium channel blocker used for managing hypertension and preterm labor. It is not indicated for treating postpartum hemorrhage as it lacks uterotonic effects.
Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"B"},"D":{"answers":"B"},"E":{"answers":"A"}}
Explanation
Rationale:
- Monitor for elevated temperature: Epidural anesthesia can mask symptoms of infection such as chorioamnionitis. Monitoring temperature helps detect early signs of infection or epidural-related complications.
- Assess for urinary retention: Epidural anesthesia often causes loss of bladder sensation, increasing the risk for urinary retention. Regular assessments are needed to determine when catheterization is required.
- Assist the client with ambulation: After epidural anesthesia, lower limb motor function may be impaired. Ambulation is unsafe due to the risk of falls and injury; bedrest is generally advised until full motor function returns.
- Inform the client to expect drowsiness: Drowsiness is not a typical side effect of epidural anesthesia; it may indicate systemic absorption or another issue. Encouraging drowsiness may mask concerning symptoms that need prompt evaluation.
- Encourage the client to turn from side to side: Repositioning helps maintain optimal uteroplacental perfusion and prevents hypotension caused by vena cava compression from aortocaval syndrome.
