Nursing Elites

1. A nurse is caring for a preterm newborn who is in an incubator to maintain a neutral thermal environment. The father of the newborn asks the nurse why this is necessary. Which of the following responses should the nurse make?

• A. Preterm newborns have a smaller body surface area than normal newborns.
• B. The added brown fat layer in a preterm newborn reduces his ability to generate heat.
• C. Preterm newborns lack adequate temperature control mechanisms.
• D. The heat in the incubator rapidly dries the sweat of preterm newborns.

Correct answer: C

Rationale: The correct answer is C because preterm newborns have immature temperature regulation mechanisms, making it difficult for them to maintain their body temperature. An incubator helps maintain a stable thermal environment. Choice A is incorrect as the body surface area is not the primary reason for needing an incubator. Choice B is incorrect because brown fat in preterm newborns actually helps generate heat. Choice D is incorrect as the purpose of the incubator is not to dry sweat but to regulate the newborn's temperature.

2. When caring for a client suspected of having hyperemesis gravidarum, which finding is a manifestation of this condition?

• A. Hgb 12.2 g/dL
• B. Urine ketones present
• C. Alanine aminotransferase 20 IU/L
• D. Blood glucose 114 mg/dL

Correct answer: B

Rationale: The correct answer is B: Urine ketones present. The presence of urine ketones indicates dehydration, which is a common manifestation of hyperemesis gravidarum. Hyperemesis gravidarum is characterized by severe nausea, vomiting, weight loss, and electrolyte imbalances due to dehydration. Monitoring for ketonuria helps assess the degree of dehydration in clients with this condition. Choices A, C, and D are incorrect because hemoglobin level, alanine aminotransferase level, and blood glucose level are not specific manifestations of hyperemesis gravidarum. While these laboratory values may be abnormal in some cases, they are not typically used to diagnose or assess the condition.

3. A client has postpartum psychosis. Which of the following actions is the nurse's priority?

• A. Reinforce the importance of taking antipsychotics as prescribed
• B. Ask the client if they have thoughts of harming themselves or their infant
• C. Monitor the infant for signs of failure to thrive
• D. Check the client's medical record for a history of bipolar disorder

Correct answer: B

Rationale: In a situation where a client has postpartum psychosis, the priority action for the nurse is to ask the client if they have thoughts of harming themselves or their infant. This is crucial to assess the risk of harm and ensure the safety of the client and the infant. While reinforcing the importance of taking antipsychotics as prescribed is essential for treatment, safety concerns take precedence. Monitoring the infant for signs of failure to thrive is important for the infant's well-being but is not the priority when the immediate safety of the client and infant is at risk. Checking the client's medical record for a history of bipolar disorder is relevant for understanding the client's medical history but is not the priority when addressing current safety concerns.

4. A nurse is developing a plan of care for a client who has preeclampsia and is receiving magnesium sulfate via a continuous IV infusion. Which of the following interventions should the nurse include in the plan?

• A. Monitor the client's blood pressure every hour.
• B. Restrict the total hourly intake to 200 mL.
• C. Monitor the FHR continuously.
• D. Administer protamine sulfate for manifestations of toxicity.

Correct answer: C

Rationale: The correct answer is C. When a client with preeclampsia is receiving magnesium sulfate via continuous IV infusion, it is crucial to monitor the fetal heart rate (FHR) continuously. Magnesium sulfate is given to prevent seizures and is considered a high-alert medication that requires close monitoring, especially of FHR and uterine contractions. Monitoring the client's blood pressure every hour, as in choice A, is important but not as crucial as continuous FHR monitoring. Restricting the total hourly intake to 200 mL, as in choice B, is not a relevant intervention for a client receiving magnesium sulfate. Administering protamine sulfate for manifestations of toxicity, as in choice D, is incorrect as protamine sulfate is not the antidote for magnesium sulfate toxicity.

5. While observing the electronic fetal heart rate monitor tracing for a client at 40 weeks of gestation in labor, a nurse should suspect a problem with the umbilical cord when she observes which of the following patterns?

• A. Early decelerations
• B. Accelerations
• C. Late decelerations
• D. Variable decelerations

Correct answer: D

Rationale: Variable decelerations can indicate umbilical cord compression, which is a concern that may arise due to the umbilical cord being compressed during labor. This compression can lead to reduced blood flow and oxygen delivery to the fetus, necessitating close monitoring and potentially interventions to alleviate the pressure on the cord. Early decelerations are typically benign and mirror the contractions, indicating fetal head compression. Accelerations are reassuring patterns that show a healthy response to fetal movement. Late decelerations are concerning as they suggest uteroplacental insufficiency, indicating potential oxygen deprivation to the fetus.
