HESI RN Exit Exam

1. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. The infant was born two weeks after his due date and is described as a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?

A. Has your son had any immunizations yet?
B. Is your son sleepy and difficult to feed?
C. Are you breastfeeding or bottle-feeding your son?
D. Were any relatives born with birth defects?

Correct answer: B

Rationale: The correct answer is B. Excessive sleepiness and difficulty feeding can be signs of hypothyroidism in infants. Asking about the infant's sleepiness and feeding pattern is crucial in assessing for hypothyroidism. Choice A is incorrect because immunizations are not directly related to hypothyroidism. Choice C is about feeding method and not specific to hypothyroidism. Choice D is unrelated as it asks about relatives with birth defects, which does not directly assess the infant's condition.

2. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which laboratory value requires immediate intervention?

A. Arterial blood gas (ABG) values
B. Serum potassium level
C. Serum sodium level
D. Blood glucose level

Correct answer: A

Rationale: The correct answer is A: Arterial blood gas (ABG) values. In a client with COPD and pneumonia, ABG values are crucial as they provide essential information about the client's respiratory status, including oxygenation and acid-base balance. Immediate intervention may be required to optimize respiratory function based on ABG results. Serum potassium, sodium, and blood glucose levels are important parameters to monitor in various conditions but are not as directly related to the respiratory status in a client with COPD and pneumonia. Therefore, they do not require immediate intervention compared to ABG values.

3. When assessing a client with left-sided heart failure, which intervention should the nurse implement first?

A. Administer oxygen therapy as prescribed.
B. Monitor the client's urine output.
C. Administer a loop diuretic as prescribed.
D. Administer morphine as prescribed.

Correct answer: A

Rationale: Administering oxygen therapy is the initial intervention for a client with left-sided heart failure. This action is crucial in improving oxygen levels and reducing pulmonary congestion. Monitoring urine output is important for assessing renal function in heart failure, but it is not the priority over ensuring adequate oxygenation. Administering loop diuretics helps manage fluid overload but should come after addressing oxygen needs. Morphine may be indicated for pain or anxiety in some cases, but it is not the primary intervention for left-sided heart failure.

4. While caring for a toddler receiving oxygen (02) via face mask, the nurse observes that the child's lips and nares are dry and cracked. Which intervention should the nurse implement?

A. Ask the mother what she usually uses on the child's lips and nose.
B. Apply a petroleum jelly (Vaseline) to the child's nose and lips.
C. Use a topical lidocaine (Zylocaine viscous) analgesic for cracked lips.
D. Use a water-soluble lubricant on affected oral and nasal mucosa.

Correct answer: D

Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.

5. A client who had a gestational trophoblastic disease (GTD) evacuated 2 days ago is being monitored for choriocarcinoma. She lives in a rural area, and her husband takes the family car to work daily, leaving her without transportation during the day. What intervention is most important for the nurse to implement?

A. Teach the client about the use of a home pregnancy test.
B. Schedule a weekly home visit to draw hCG values.
C. Make a 5-week follow-up appointment with the healthcare provider.
D. Begin chemotherapy administration during the first home visit.

Correct answer: B

Rationale: Scheduling weekly home visits to monitor hCG levels is critical for early detection of choriocarcinoma, a potential complication of GTD. Choice A is incorrect because a home pregnancy test is not the appropriate method to monitor for choriocarcinoma. Choice C is less frequent than necessary for close monitoring. Choice D is incorrect as chemotherapy administration should be based on confirmed diagnosis and treatment plan, not initiated during the first home visit.
