Question 1 of 9

A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

Correct Answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

Question 2 of 9

A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

Correct Answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

Question 3 of 9

A patient has acute bronchitis with a nonproductive cough and wheezes. Which topic should the nurse plan to include in the teaching plan?

Correct Answer: C

Rationale: In acute bronchitis, which is often viral, cough suppressants can help manage the symptoms of a nonproductive cough. Antibiotics are not typically used in acute bronchitis unless there are systemic symptoms indicating a bacterial infection. Limiting oral fluid intake is not recommended; in fact, maintaining adequate hydration is important. Safety concerns with home oxygen therapy may not be directly relevant to the management of acute bronchitis.

Question 4 of 9

While caring for a patient with respiratory disease, the nurse observes that the patient's SpO2 drops from 93% to 88% while the patient is ambulating in the hallway. What is the priority action of the nurse?

Correct Answer: C

Rationale: The drop in SpO2 to 88% indicates that the patient is hypoxemic and needs supplemental oxygen when exercising. Administering PRN supplemental oxygen is the priority action to correct the hypoxemia and ensure adequate oxygenation during activity. Notifying the healthcare provider can be done after stabilizing the patient's oxygen levels. Documenting the response to exercise is important but secondary to addressing the immediate hypoxemia. Encouraging the patient to pace activity is not sufficient to address the acute drop in SpO2 and provide the necessary oxygen support.

Question 5 of 9

When obtaining a health history and physical assessment for a 36-year-old female patient with possible multiple sclerosis (MS), the nurse should

Correct Answer: B

Rationale: When assessing a patient for possible multiple sclerosis (MS), it is important to inquire about urinary tract problems as they are common symptoms of the condition, such as incontinence or retention. Chest pain is not typically associated with MS, so assessing for its presence is not a priority. Inspecting the skin for rashes or discoloration is not a typical manifestation of MS. Additionally, a decrease in libido, rather than an increase, is more commonly seen in patients with MS. Therefore, the most appropriate action for the nurse in this scenario is to inquire about urinary tract problems.

Question 6 of 9

A 49-year-old patient with multiple sclerosis (MS) is to begin treatment with glatiramer acetate (Copaxone). Which information will the nurse include in patient teaching?

Correct Answer: C

Rationale: When initiating treatment with glatiramer acetate (Copaxone), patient education should focus on teaching the patient how to draw up and administer injections of the medication. Copaxone is administered via self-injection, hence understanding the correct technique is crucial for successful treatment. Recommendations regarding fluid intake or the need to avoid driving heavy machinery are not directly related to glatiramer acetate therapy. Additionally, while discussing contraceptive methods may be important, the use of oral contraceptives does not specifically contraindicate the use of glatiramer acetate.

Question 7 of 9

The nurse caring for Mrs. J is prepared to suction her endotracheal tube. Which of the following interventions will reduce hypoxia during this procedure?

Correct Answer: A

Rationale: Before suctioning a client's endotracheal tube, it is essential to hyperoxygenate the client for approximately 30 to 60 seconds. Hyperoxygenation helps increase oxygen delivery to the tissues, reducing the risk of hypoxia during and after the suctioning procedure. Administering fluid into the tube before suctioning (Choice B) is unnecessary and can lead to complications. Suctioning for no longer than 30 seconds at a time (Choice C) is a general guideline but does not specifically address reducing hypoxia. Waiting 30 seconds after suctioning before attempting again (Choice D) may lead to inadequate oxygenation and potential hypoxia, making it less effective in preventing this complication compared to hyperoxygenation prior to suctioning.

Question 8 of 9

A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?

Correct Answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

Question 9 of 9

A patient with a possible pulmonary embolism complains of chest pain and difficulty breathing. The nurse finds a heart rate of 142 beats/minute, blood pressure of 100/60 mmHg, and respirations of 42 breaths/minute. Which action should the nurse take first?

Correct Answer: D

Rationale: The patient presents with symptoms indicative of a pulmonary embolism (PE), such as chest pain, difficulty breathing, tachycardia, hypotension, and tachypnea. Elevating the head of the bed to a semi-Fowler's position is the priority to improve ventilation and gas exchange. This intervention should be initiated promptly to optimize oxygenation. Subsequent actions, such as notifying the healthcare provider, preparing for a spiral CT scan, and administering anticoagulant therapy, can follow after the patient's position is adjusted. The spiral CT scan is typically used to confirm the diagnosis of PE, and anticoagulant therapy is initiated upon confirmation of the diagnosis by the healthcare provider. Therefore, the immediate focus is on improving the patient's respiratory status by elevating the head of the bed.
