Nursing Elites

1. A child admitted with diabetic ketoacidosis is demonstrating Kussmaul respirations. The nurse determines that the increased respiratory rate is a compensatory mechanism for which acid-base alteration?

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

Correct answer: D

Rationale: Kussmaul respirations are deep, rapid breathing patterns observed in metabolic acidosis, such as diabetic ketoacidosis. In this condition, the body tries to compensate for the acidic environment by increasing the respiratory rate to eliminate excess carbon dioxide (CO2) and decrease the acid levels, thereby helping to correct the acid-base imbalance. Therefore, the correct answer is metabolic acidosis.

2. What information should the nurse provide to parents of a 3-year-old boy with Duchenne muscular dystrophy who inquire about the disease and future children?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family
• B. The striated muscle groups of males can be impacted by a lack of the protein dystrophin in their mothers
• C. The male infant had a viral infection that went unnoticed and untreated so muscle damage was incurred
• D. Birth trauma with a breech vaginal birth causes damage to the spinal cord, thus weakening the muscles

Correct answer: A

Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons. Choice B is incorrect as it inaccurately implies that the lack of dystrophin in mothers impacts their sons' muscle groups. Choice C is incorrect as it suggests a viral infection caused the muscle damage, which is not the case with Duchenne muscular dystrophy. Choice D is incorrect as it attributes the muscle weakness to birth trauma instead of the genetic nature of the disorder.

3. A 14-year-old client with type 1 diabetes is participating in a school sports event. The nurse provides education to the client about managing blood glucose levels during physical activity. Which statement by the client indicates a need for further teaching?

• A. I should check my blood sugar before and after exercise
• B. I need to eat a snack before I start playing
• C. If my blood sugar is high, I should skip my insulin dose before exercise
• D. I should carry a fast-acting carbohydrate with me during sports

Correct answer: C

Rationale: The correct answer is C. Skipping the insulin dose when blood sugar is high before exercise can be harmful. It is essential to manage blood glucose levels carefully during physical activity, which may require adjustments to insulin doses but skipping doses is not recommended. Checking blood sugar before and after exercise (Choice A) helps in monitoring and managing blood glucose levels. Eating a snack before playing (Choice B) can help maintain blood sugar levels during physical activity. Carrying a fast-acting carbohydrate (Choice D) is important in case of low blood sugar during sports to quickly raise glucose levels. Therefore, the client needs further teaching on the importance of not skipping insulin doses even if blood sugar is high before exercise.

4. A 2-year-old child with heart failure (HF) is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

• A. Determine the pulse deficit.
• B. Administer the scheduled dose.
• C. Calculate the safe dose range.
• D. Review the serum digoxin level.

Correct answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario since the heart rate of 128 bpm is within an acceptable range for a 2-year-old child with heart failure. Monitoring for signs of digoxin toxicity is important; however, the immediate action required is to administer the scheduled dose as prescribed based on the heart rate assessment.

5. A 14-year-old adolescent with a history of substance abuse is brought to the emergency department by the parents, who suspect that the adolescent has relapsed. What is the nurse’s priority action?

• A. Obtain a urine sample for toxicology screening
• B. Discuss treatment options with the parents
• C. Establish a therapeutic relationship with the adolescent
• D. Administer a medication to reverse the effects of the substance

Correct answer: A

Rationale: In this scenario, the nurse's priority action should be to obtain a urine sample for toxicology screening. This step is crucial in identifying the substances involved in the relapse, which will guide appropriate treatment strategies. By knowing the specific substances, healthcare providers can tailor treatment plans effectively. Establishing a therapeutic relationship and discussing treatment options come after obtaining necessary diagnostic information to ensure a comprehensive care plan. Administering a medication to reverse substance effects is not the initial priority; identification of the substances through toxicology screening should precede any treatment intervention.
