1. In discussing sex hormone production with the patient, the nurse should describe that testosterone is normally secreted in response to
- A. sexual arousal.
- B. stimulation by luteinizing hormone.
- C. ACTH release by the adrenal cortex.
- D. decreased cortisol levels.
Correct answer: B
Rationale: Testosterone production is regulated by the hypothalamic-pituitary-gonadal axis. Luteinizing hormone (LH) stimulates the Leydig cells in the testes to produce testosterone. Therefore, the correct answer is B. Choice A, 'sexual arousal,' is incorrect because testosterone secretion is not directly linked to arousal but rather to hormonal stimulation. Choice C, 'ACTH release by the adrenal cortex,' is incorrect as testosterone production is not primarily regulated by adrenocorticotropic hormone (ACTH). Choice D, 'decreased cortisol levels,' is also incorrect as cortisol and testosterone are regulated by separate endocrine pathways.
2. A nurse is preparing to administer enteral feedings to a client with an NG tube. Which action should the nurse take first?
- A. Flush the tube with 100 mL of water
- B. Verify tube placement
- C. Elevate the head of the bed
- D. Measure the residual gastric volume
Correct answer: B
Rationale: Verifying tube placement is the priority action the nurse should take before administering enteral feedings. This step ensures that the NG tube is correctly positioned, reducing the risk of complications such as aspiration pneumonia. Flushing the tube with water, elevating the head of the bed, and measuring residual gastric volume are important steps in enteral feeding administration but come after verifying tube placement. Flushing the tube with water helps clear the tubing, elevating the head of the bed reduces the risk of aspiration, and measuring residual gastric volume helps assess the client's tolerance to feedings.
3. Which nursing action will best promote patient safety when administering medications?
- A. Check the patient's wristband before administering medications.
- B. Confirm the patient's allergies prior to administration.
- C. Document the medications immediately after administration.
- D. Prepare medications at the medication cart to minimize distractions.
Correct answer: B
Rationale: Confirming the patient's allergies before administering medications is crucial for patient safety as it helps prevent adverse reactions. Checking the patient's wristband is important for identification but may not directly impact medication safety. Documenting medications after administration is necessary but does not primarily promote safety during administration. Preparing medications at the medication cart, rather than the nurse's station, is preferred to ensure accuracy and proper medication handling, but it is not directly related to confirming allergies for safety.
4. The nurse is assessing a 3-day-old breastfed newborn who weighed 3400 g (7 pounds, 8 oz) at birth. The infant’s mother is now concerned because the infant weighs 3147 g (6 pounds, 15 oz). The most appropriate nursing intervention is what?
- A. Recommend supplemental feedings of formula.
- B. Explain that this weight loss is within normal limits.
- C. Assess the child further to determine the cause of excessive weight loss.
- D. Encourage the mother to express breast milk for bottle-feeding the infant.
Correct answer: B
Rationale: A neonate normally loses about 10% of the birth weight by age 3 to 4 days. The birth weight is usually regained by the 10th day of life. In this case, the weight loss from 3400 g to 3147 g is within the expected range. Therefore, the most appropriate action is to explain to the mother that this weight loss is within normal limits. Choice A is incorrect because supplemental feedings of formula are not indicated for this expected weight loss in a breastfed newborn. Choice C is incorrect as there is no evidence to suggest excessive weight loss at this point. Choice D is unnecessary at this stage and may not align with the current situation of normal weight loss post-birth.
5. What should the nurse include in the discharge instructions for the parents of an infant diagnosed with acute otitis media?
- A. Keep the baby in an elevated position during sleep
- B. Administer an antibiotic
- C. Place the baby to sleep with a bottle
- D. Administer acetaminophen (Tylenol) to relieve discomfort
Correct answer: D
Rationale: Acetaminophen (Tylenol) is recommended to help relieve the discomfort associated with acute otitis media, such as pain and fever. Elevating the baby's head during sleep can also help with drainage and relieve pressure, making choice A incorrect. Administering an antibiotic may be necessary for bacterial otitis media but is not usually the first-line treatment for acute otitis media, so choice B is incorrect. Placing the baby to sleep with a bottle can increase the risk of ear infections due to the pooling of milk around the Eustachian tube, so choice C is incorrect.
