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. The practical nurse (PN) is caring for an adolescent who has been diagnosed with mononucleosis. Which activity should the PN advise the adolescent to avoid?
- A. Playing video games.
- B. Drinking caffeinated beverages.
- C. Participating in contact sports.
- D. Eating spicy foods.
Correct answer: C
Rationale: Contact sports should be avoided in mononucleosis due to the risk of spleen rupture, which is a serious complication of the disease. The spleen can enlarge in mononucleosis, making it more susceptible to injury from contact sports, potentially leading to a life-threatening situation if rupture occurs.
3. A 2-year-old girl is brought to the clinic by her 17-year-old mother. When the nurse observes that the child is drinking sweetened soda from her bottle, what information should the nurse discuss with this mother?
- A. A 2-year-old should be speaking in 2-word phrases
- B. Dental caries is associated with drinking soda
- C. Drinking soda is related to childhood obesity
- D. Toddlers should be sleeping 10 hours a night
Correct answer: B
Rationale: Dental caries are a common concern when children consume sweetened sodas regularly.
4. Which nursing intervention is most important to include in the plan of care for a child with acute glomerulonephritis?
- A. Encourage fluid intake.
- B. Promote complete bed rest.
- C. Weigh the child daily.
- D. Administer vitamin supplements.
Correct answer: C
Rationale: Weighing the child daily is crucial in managing a child with acute glomerulonephritis as it helps in monitoring fluid retention, which is a key concern in this condition. Daily weight monitoring allows healthcare providers to assess changes in fluid status and adjust treatment accordingly. It is an essential component of the care plan to ensure the child's health status is closely monitored during the management of acute glomerulonephritis. Encouraging fluid intake (Choice A) is generally beneficial but may not be the priority in this case where fluid retention needs close monitoring. Promoting complete bed rest (Choice B) can be important but may not be the most critical intervention. Administering vitamin supplements (Choice D) may not directly address the immediate concerns related to fluid retention in acute glomerulonephritis.
5. The nurse is assessing a 4-month-old infant who has just received routine immunizations. The mother reports that the baby has been fussy and has a low-grade fever since the immunizations. What is the best response by the nurse?
- A. These are common side effects and should resolve within a few days
- B. Your baby may be having an allergic reaction to the immunizations
- C. You should bring your baby to the clinic immediately for evaluation
- D. You should give your baby aspirin to help with the fever
Correct answer: A
Rationale: The correct response by the nurse is to reassure the mother that fussiness and low-grade fever are common side effects of immunizations in infants and should resolve within a few days. It is essential to educate the mother about these expected reactions to alleviate her concerns. Choice B is incorrect because allergic reactions to immunizations usually present with more severe symptoms such as difficulty breathing or swelling. Choice C is not warranted unless there are concerning symptoms present. Choice D is inappropriate as aspirin is contraindicated in infants due to the risk of Reye's syndrome.
