Nursing Elites

1. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?

• A. Metabolic alkalosis.
• B. Respiratory acidosis.
• C. Metabolic acidosis.
• D. Respiratory alkalosis.

Correct answer: A

Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.

2. A school-age child with a history of type 1 diabetes mellitus is brought to the emergency department with confusion and rapid breathing. The practical nurse (PN) suspects diabetic ketoacidosis (DKA). Which initial intervention should the PN anticipate?

• A. Administer subcutaneous insulin.
• B. Give oral glucose tablets.
• C. Start intravenous fluids.
• D. Administer oxygen therapy.

Correct answer: C

Rationale: Intravenous fluids are typically the initial intervention in diabetic ketoacidosis (DKA) to treat dehydration and stabilize the patient's condition. The fluid replacement helps correct electrolyte imbalances and improve perfusion, which are crucial in managing DKA. Insulin therapy follows after fluid resuscitation to address the underlying cause of DKA, which is the lack of insulin leading to increased ketone production. Administering subcutaneous insulin (Choice A) would be premature without first addressing the dehydration and electrolyte imbalances. Giving oral glucose tablets (Choice B) is contraindicated in DKA as the patient already has high blood glucose levels. Administering oxygen therapy (Choice D) may be necessary based on the patient's condition, but addressing dehydration with intravenous fluids is the priority intervention in DKA.

3. A child with Graves' disease who is taking propranolol (Inderal) is seen in the clinic. The nurse should monitor the child for which therapeutic response?

• A. Increased weight gain
• B. Decreased heart rate
• C. Reduced headaches
• D. Diminished fatigue

Correct answer: B

Rationale: The correct answer is B: 'Decreased heart rate.' Propranolol is a beta-blocker commonly used to manage symptoms of hyperthyroidism, including tachycardia. Monitoring for a decreased heart rate is important as it indicates the drug's therapeutic response in controlling the elevated heart rate associated with Graves' disease. Choices A, C, and D are incorrect because weight gain, reduced headaches, and diminished fatigue are not typical therapeutic responses to propranolol in the context of managing Graves' disease.

4. In a 12-year-old child with a history of epilepsy brought to the emergency department after experiencing a 10-minute seizure, what is the nurse’s priority intervention?

• A. Administer oxygen
• B. Administer antiepileptic medication as prescribed
• C. Monitor the child’s vital signs
• D. Check the child’s blood glucose level

Correct answer: B

Rationale: Administering antiepileptic medication as prescribed is the priority intervention in a child with a history of epilepsy who experienced a prolonged seizure. This action is crucial to stop the seizure and prevent further complications associated with prolonged seizure activity. Administering oxygen may be necessary, but the priority is to stop the seizure. Monitoring vital signs and checking blood glucose levels are important but secondary to administering antiepileptic medication to manage the seizure.

5. A 12-year-old child is admitted to the hospital with a diagnosis of osteomyelitis. Which finding should the nurse expect during the assessment?

• A. Localized pain and swelling
• B. Generalized joint stiffness
• C. Pain in the muscles
• D. Limited range of motion in the limbs

Correct answer: A

Rationale: In osteomyelitis, an infection of the bone, patients typically present with localized pain, swelling, and warmth over the affected bone. This is due to the inflammatory response in the bone tissue. Generalized joint stiffness, pain in the muscles, and limited range of motion in the limbs are not specific to osteomyelitis and are more commonly associated with other conditions.
