Oxygenation NCLEX Questions Questions
Question 1 of 5
A client with pneumonia is receiving antibiotics. Which action is most important to ensure effective treatment?
Correct Answer: B
Rationale: The correct answer is B. Collecting a sputum culture before administering antibiotics is crucial to identify the specific pathogen causing the pneumonia. This allows for targeted antibiotic therapy, improving treatment effectiveness. Encouraging oral fluid intake (A) is important but not as critical as identifying the pathogen. Administering antipyretics (C) may provide symptomatic relief but does not address the underlying infection. Monitoring white blood cell count (D) is general and may not provide specific information needed for effective treatment.
Question 2 of 5
A patient arrives in the emergency department with a stab wound to the chest. What action should the nurse take?
Correct Answer: D
Rationale: The correct answer is D because taping a nonporous dressing on three sides over the wound creates a flutter valve effect, allowing air to escape but not re-enter, preventing tension pneumothorax. Choice A (keeping the head of the bed flat) may worsen respiratory distress. Choice B (covering the wound tightly with an occlusive dressing) can lead to tension pneumothorax. Choice C (positioning the patient with the left chest dependent) is incorrect and may not address the immediate issue of air escaping from the wound.
Question 3 of 5
A patient with asthma is prescribed salmeterol. Which instruction should the nurse provide?
Correct Answer: C
Rationale: The correct answer is C because salmeterol is a long-acting beta agonist used for maintenance treatment of asthma, not for acute attacks. Daily use helps prevent asthma symptoms by providing long-term bronchodilation. Choices A and B are incorrect as salmeterol is not for acute attacks or require food with it. Choice D is not necessary for salmeterol, as it does not typically affect pulse rate significantly.
Question 4 of 5
A patient with chronic obstructive pulmonary disease (COPD) is prescribed theophylline. Which finding would be most concerning?
Correct Answer: B
Rationale: The correct answer is B. A heart rate of 112 bpm is concerning in a patient taking theophylline because it can indicate theophylline toxicity, which can lead to serious cardiac arrhythmias. Theophylline has a narrow therapeutic index, and levels above 20 mcg/mL can be toxic. Nausea, vomiting, and mild hand tremors are common side effects of theophylline but are not typically indicative of toxicity. Monitoring the theophylline level is important, but a level of 15 mcg/mL alone does not indicate toxicity. In summary, the elevated heart rate is the most concerning finding as it suggests potential theophylline toxicity, while the other options are more commonly seen as side effects without indicating toxicity.
Question 5 of 5
The nurse prepares a patient for bronchoscopy. Which patient statement indicates the need for further pre-procedure teaching?
Correct Answer: C
Rationale: Correct Answer: C Rationale: 1. The patient statement "I can drive myself home after the procedure" indicates a lack of understanding of the sedative effects of the procedure. 2. Sedation is commonly used during bronchoscopy, impairing the patient's ability to drive safely. 3. Patients should arrange for someone to drive them home post-procedure to ensure their safety and comply with medical guidelines. Summary: A: Correct - Fasting before bronchoscopy is necessary to reduce the risk of aspiration. B: Incorrect - Throat discomfort is a common post-procedure symptom. D: Incorrect - Allergies to anesthesia should be reported for safety reasons.
