Nursing Elites

1. A client is receiving digoxin (Lanoxin) 0.25 mg daily. The health care provider has written a new order to give metoprolol (Lopressor) 25 mg B.I.D. In assessing the client prior to administering the medications, which of the following should the nurse report immediately to the health care provider?

• A. Blood pressure 94/60 mm Hg
• B. Heart rate 76 bpm
• C. Urine output 50 ml/hour
• D. Respiratory rate 16 bpm

Correct answer: A

Rationale: The correct answer is 'Blood pressure 94/60 mm Hg.' Both digoxin and metoprolol decrease the heart rate. Metoprolol specifically affects blood pressure. Therefore, the heart rate and blood pressure need to be within normal range (HR 60-100 bpm; systolic BP above 100 mm Hg) to safely administer both medications. A blood pressure of 94/60 mm Hg indicates hypotension, which could be exacerbated by metoprolol, necessitating immediate reporting to the healthcare provider. Choices B, C, and D are within normal limits and do not pose immediate risks related to the administration of these medications.

2. The clinic nurse reviews the record of an infant and notes that the primary health care provider (PHCP) has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek health care for the infant?

• A. Diarrhea
• B. Projectile vomiting
• C. Regurgitation of feedings
• D. Constipation

Correct answer: C

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is characterized by the absence of ganglion cells in the rectum and other parts of the affected intestine. Clinical manifestations of Hirschsprung's disease include chronic constipation with pellet-like or ribbon-like foul-smelling stools, delayed or absent passage of meconium in the neonatal period, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive. In the case of an infant with suspected Hirschsprung's disease, regurgitation of feedings is a sign that may have led the mother to seek healthcare. This symptom can be associated with the bowel dysfunction and obstruction seen in Hirschsprung's disease. Options A, B, and D are not typically associated with Hirschsprung's disease. Diarrhea is not a common symptom, projectile vomiting is not a typical presentation, and constipation, while a symptom of the disease, is not the sign that would most likely prompt a visit to seek healthcare in an infant suspected of having Hirschsprung's disease.

3. A patient's chart indicates a history of ketoacidosis. Which of the following would you not expect to see with this patient if this condition were acute?

• A. Vomiting
• B. Extreme Thirst
• C. Weight gain
• D. Acetone breath smell

Correct answer: C

Rationale: In acute ketoacidosis, a patient typically experiences rapid weight loss due to the body burning fat and muscle for energy in the absence of sufficient insulin. Therefore, weight gain would not be expected. Vomiting may occur due to the metabolic disturbances associated with ketoacidosis. Extreme thirst is a common symptom as the body tries to compensate for dehydration. Acetone breath smell is a classic sign of ketoacidosis as acetone is one of the ketones produced during this condition.

4. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

5. An infant weighed 7 pounds 8 ounces at birth. If growth occurs at a normal rate, what would be the expected weight at 6 months of age?

• A. Double the birth weight
• B. Triple the birth weight
• C. Gain 6 ounces each week
• D. Add 2 pounds each month

Correct answer: A

Rationale: Infants typically double their birth weight by 6 months of age as part of normal growth and development. This doubling of weight is a common milestone used by healthcare providers to assess a baby's growth progress. Tripling the birth weight or adding 2 pounds each month would result in excessive weight gain, which is not typical or healthy for an infant. Similarly, gaining 6 ounces each week would also lead to rapid and abnormal weight gain, making it an incorrect choice.
