Nursing Elites

1. A 30-year-old woman is experiencing anaphylaxis from a bee sting. Emergency personnel have been called. The nurse notes the woman is breathing but short of breath. Which of the following interventions should the nurse do first?

• A. Initiate cardiopulmonary resuscitation
• B. Check for a pulse
• C. Ask the woman if she carries an emergency medical kit
• D. Stay with the woman until help comes

Correct answer: C

Rationale: In a situation where a patient is experiencing anaphylaxis, it is crucial to act swiftly. Asking the woman if she carries an emergency medical kit is the most appropriate initial intervention. Many individuals with a history of anaphylaxis carry epinephrine auto-injectors, such as epi-pens, which can be life-saving in such situations. Initiating cardiopulmonary resuscitation (CPR) is not indicated as the patient is breathing but short of breath, and CPR is not the first-line intervention for anaphylaxis. Checking for a pulse, though important, is not the initial priority in managing anaphylaxis. Staying with the woman until help arrives is essential for providing support and monitoring her condition, but confirming the availability of an emergency medical kit takes precedence to promptly address the anaphylactic reaction.

2. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

3. 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.

4. A patient with acute shortness of breath is admitted to the hospital. Which action should the nurse take during the initial assessment of the patient?

• A. Ask the patient to lie down to complete a full physical assessment.
• B. Briefly ask specific questions about this episode of respiratory distress.
• C. Complete the admission database to check for allergies before treatment.
• D. Delay the physical assessment to first complete pulmonary function tests.

Correct answer: B

Rationale: When a patient presents with acute shortness of breath, the initial assessment should focus on gathering specific information relevant to the current episode of respiratory distress. A comprehensive health history or full physical examination can be deferred until the acute distress has been addressed. Asking specific questions helps determine the cause of the distress and guides appropriate treatment. While checking for allergies is important, completing the entire admission database is not a priority during the initial assessment. Likewise, delaying the physical assessment for pulmonary function tests is not recommended as the immediate focus should be on addressing the acute respiratory distress before ordering further diagnostic tests or interventions.

5. Which of the following medications taken by the patient is least likely to cause urine discoloration?

• A. Sulfasalazine
• B. Levodopa
• C. Phenolphthalein
• D. Aspirin

Correct answer: D

Rationale: The correct answer is Aspirin. Aspirin is not known to cause urine discoloration. Sulfasalazine is associated with causing orange-yellow discoloration of urine. Levodopa can cause darkening of urine to a brown or black color. Phenolphthalein has been linked to pink or red discoloration of urine. Therefore, among the options provided, Aspirin is the medication least likely to cause urine discoloration.
