Nursing Elites

1. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?

• A. Administer bicarbonate.
• B. Complete a head-to-toe assessment.
• C. Place the patient on high-flow oxygen.
• D. Obtain repeat arterial blood gases (ABGs).

Correct answer: C

Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.

2. The nurse palpates the posterior chest while the patient says 99 and notes absent fremitus. What action should the nurse take next?

• A. Auscultate anterior and posterior breath sounds bilaterally
• B. Encourage the patient to turn, cough, and deep breathe
• C. Review the chest x-ray report for evidence of pneumonia
• D. Palpate the anterior chest and observe for barrel chest

Correct answer: A

Rationale: To assess for tactile fremitus, the nurse should use the palms of the hands to assess for vibration when the patient repeats a word or phrase such as '99'. After noting absent fremitus, the nurse should then auscultate the lungs to assess for the presence or absence of breath sounds. Absent fremitus may be noted with conditions like pneumothorax or atelectasis. The vibration is increased in conditions such as pneumonia, lung tumors, thick bronchial secretions, and pleural effusion. Encouraging the patient to turn, cough, and deep breathe is an appropriate intervention for atelectasis, but assessing breath sounds takes priority. Fremitus is decreased if the hand is farther from the lung or the lung is hyperinflated (barrel chest). Palpating the anterior chest for fremitus is less effective due to the presence of large muscles and breast tissue, making auscultation a more appropriate next step.

3. Diabetic patients are more prone to ____________ than other people without this chronic disorder.

• A. infection
• B. increased oxygen saturation
• C. low fibrinogen
• D. constipation

Correct answer: A

Rationale: Diabetic patients are more prone to infection than other people without this chronic disorder. Diabetes weakens the immune system and impairs the body's ability to fight off infections, making individuals with diabetes more susceptible to various types of infections. Increased oxygen saturation, low fibrinogen, and constipation are not directly related to diabetes or the increased infection risk associated with the condition. Increased oxygen saturation is actually a positive health indicator, low fibrinogen levels are not a common issue in diabetes, and constipation is not a primary concern when comparing diabetic patients to others without the condition.

4. A patient is scheduled for a computed tomography (CT) of the chest with contrast media. Which assessment finding should the nurse immediately report to the health care provider?

• A. Patient is claustrophobic.
• B. Patient is allergic to shellfish.
• C. Patient recently used a bronchodilator inhaler.
• D. Patient is not able to remove a wedding band.

Correct answer: B

Rationale: The correct answer is that the patient is allergic to shellfish. This is crucial because the contrast media used in CT scans is iodine-based, and individuals with iodine allergies, such as those allergic to shellfish, are at risk of adverse reactions. It is important to identify and address this allergy to prevent potential complications. The other options do not directly impact the safety or effectiveness of the CT scan with contrast media. Claustrophobia can be managed with patient support, the recent use of a bronchodilator inhaler does not typically affect the CT procedure, and not being able to remove a wedding band is not a critical concern for the scan itself.

5. A patient is admitted with active tuberculosis (TB). The nurse should question a healthcare provider's order to discontinue airborne precautions unless which assessment finding is documented?

• A. Chest x-ray shows no upper lobe infiltrates.
• B. TB medications have been taken for 6 months.
• C. Mantoux testing shows an induration of 10 mm.
• D. Three sputum smears for acid-fast bacilli are negative.

Correct answer: D

Rationale: The correct answer is D: Three sputum smears for acid-fast bacilli are negative. Negative sputum smears indicate that Mycobacterium tuberculosis is not present in the sputum, and the patient cannot transmit the bacteria by the airborne route. This finding is crucial for discontinuing airborne precautions. Choice A is incorrect because chest x-rays do not determine the presence of active TB for transmission precautions. Choice B is not directly related to the infectiousness of TB; completing a 6-month course of medication is important for treatment but does not confirm the absence of active disease or infectiousness. Choice C is not relevant to assessing infectiousness; Mantoux testing measures exposure to TB but does not confirm the absence of active infection or infectiousness.
