Nursing Elites

1. A healthcare provider is assessing a newborn who has a coarctation of the aorta. Which of the following should the provider recognize as a clinical manifestation of coarctation of the aorta?

• A. Increased blood pressure in the arms with decreased blood pressure in the legs
• B. Decreased blood pressure in the arms with increased blood pressure in the legs
• C. Increased blood pressure in both the arms and the legs
• D. Decreased blood pressure in both the arms and the legs

Correct answer: A

Rationale: The correct answer is increased blood pressure in the arms with decreased blood pressure in the legs. Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, leading to increased blood pressure in the upper extremities and decreased blood pressure in the lower extremities due to decreased blood flow beyond the narrowing. Choice B is incorrect because coarctation of the aorta does not lead to increased blood pressure in the legs. Choice C is incorrect because increased blood pressure in both the arms and legs is not a typical manifestation of coarctation of the aorta. Choice D is incorrect because decreased blood pressure in both the arms and legs is not characteristic of coarctation of the aorta.

2. An adolescent is being taught about levonorgestrel contraception by a school nurse. What information should the nurse include in the teaching?

• A. You should take the medication within 72 hours following unprotected sexual intercourse.
• B. Do not take this medication if you are on an oral contraceptive.
• C. If you do not start your period within 5 days of taking this medication, you will need a pregnancy test.
• D. One dose of this medication will prevent pregnancy for 14 days after taking it.

Correct answer: A

Rationale: Levonorgestrel is an emergency contraceptive that works by inhibiting ovulation to prevent conception. It is most effective when taken as soon as possible within 72 hours following unprotected sexual intercourse. Therefore, the nurse should instruct the adolescent to take the medication promptly to maximize its effectiveness. Choice B is incorrect because levonorgestrel can be used even if the individual is on oral contraceptives. Choice C is incorrect as the efficacy of levonorgestrel is not determined by the onset of menstruation. Choice D is incorrect because levonorgestrel is a single-dose emergency contraceptive and does not provide protection for 14 days after ingestion.

3. 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.

4. A healthcare provider is assessing a newborn 1 hr after birth. Which of the following respiratory rates is within the expected reference range for a newborn?

• A. 22/min
• B. 48/min
• C. 100/min
• D. 110/min

Correct answer: B

Rationale: The expected respiratory rate for a newborn is between 30 to 60 breaths per minute. A rate of 48 breaths per minute falls within this range, indicating normal respiratory function for a newborn. Choice A (22/min) is below the expected range, Choices C (100/min) and D (110/min) are above the expected range for a newborn's respiratory rate.

5. 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.
