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. A 3-year-old child is admitted to the hospital with a diagnosis of pneumonia. The nurse notes that the child has a fever and is breathing rapidly. What is the nurse’s priority action?

• A. Administer antipyretic medication
• B. Obtain a chest X-ray
• C. Start the child on oxygen therapy
• D. Notify the healthcare provider

Correct answer: C

Rationale: In a child with pneumonia who is breathing rapidly, the priority action for the nurse is to start the child on oxygen therapy. This intervention is essential to ensure adequate oxygenation, which is crucial in managing respiratory distress and preventing complications associated with hypoxia. Administering antipyretic medication (Choice A) may help reduce the fever but does not address the immediate need for oxygen therapy. Obtaining a chest X-ray (Choice B) is important for diagnosis but providing oxygen is more urgent. Notifying the healthcare provider (Choice D) can be done after initiating oxygen therapy to update on the patient's condition.

3. A 6-month-old female is scheduled to receive diphtheria, tetanus toxoid, and acellular pertussis vaccine (DTaP) and IPV (inactivated poliovirus vaccine) immunizations. She is recovering from a cold but is otherwise healthy and afebrile. Her 5-year-old sister is receiving chemotherapy. Which considerations should the nurse make for this situation?

• A. DTaP and IPV can be safely given to the infant at the scheduled time.
• B. DTaP and IPV are contraindicated because the infant has a cold.
• C. IPV is contraindicated because her sister is immunocompromised.
• D. DTaP is contraindicated because her sister is immunocompromised.

Correct answer: A

Rationale: DTaP and IPV can be safely administered to a child with a mild illness like a cold, even if there is an immunocompromised family member, as these vaccines do not contain live viruses. It is important to ensure that the child is otherwise healthy and afebrile before administering the vaccines. The presence of a cold is not a contraindication for receiving DTaP and IPV vaccines. Choice A is correct because the infant can receive both vaccines as scheduled. Choice B is incorrect as having a cold does not contraindicate DTaP and IPV administration. Choice C is incorrect because IPV is not contraindicated due to the sister's immunocompromised status. Choice D is incorrect as both DTaP and IPV can be given in this scenario.

4. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

5. An adolescent female who is leaning forward with her hands on her knees to breathe tells the practical nurse that she has been using triamcinolone (Azmacort) inhalation aerosol before coming to the clinic. Which action should the PN implement?

• A. Obtain vital signs and assess breath sounds for wheezing.
• B. Collect a blood sample for white blood cell count.
• C. Give the client a nebulizer breathing treatment.
• D. Administer another dose of Azmacort.

Correct answer: A

Rationale: When a patient presents with breathing difficulties, the first action should be to assess vital signs and breath sounds to evaluate the severity of the condition. This assessment will provide crucial information to determine the appropriate course of action and treatment. Collecting a blood sample for a white blood cell count, giving a nebulizer treatment, or administering another dose of Azmacort would not be the initial priority in this situation. Therefore, option A is the correct choice as it focuses on assessing the patient's respiratory status to guide further interventions.
