1. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?
- A. Metabolic acidosis.
- B. Respiratory acidosis.
- C. Metabolic alkalosis.
- D. Respiratory alkalosis.
Correct answer: B
Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.
2. A client with diabetes mellitus presents with confusion and diaphoresis. What is the priority nursing action?
- A. Check the blood glucose level
- B. Administer insulin immediately
- C. Offer a high-protein snack
- D. Place the client in a supine position
Correct answer: A
Rationale: The correct answer is to check the blood glucose level. In a client with diabetes mellitus presenting with confusion and diaphoresis, it is important to assess the blood glucose level first to determine if the symptoms are due to hypoglycemia. Administering insulin immediately (Choice B) without knowing the blood glucose level can worsen the condition if the client is hypoglycemic. Offering a high-protein snack (Choice C) is not appropriate as the severity of hypoglycemia is unknown, and placing the client in a supine position (Choice D) is not the priority action for these symptoms.
3. A client who experienced partial-thickness burns with over 50% body surface area (BSA) 2 weeks ago suddenly becomes restless and agitated.
- A. Increase the room temperature.
- B. Assess the oxygen saturation.
- C. Continue to monitor vital signs.
- D. Notify the rapid response team.
Correct answer: D
Rationale: In a burn patient with sudden restlessness and agitation, it is crucial to consider hypoxia or other critical conditions. As such, notifying the rapid response team is the most appropriate action to ensure prompt assessment and intervention. Increasing room temperature (Choice A) is not the priority in this scenario. While monitoring vital signs (Choice C) is important, the sudden change in behavior warrants immediate action. Assessing oxygen saturation (Choice B) is a step in the right direction, but involving the rapid response team ensures a comprehensive evaluation and timely management of the patient's condition.
4. While performing a skin assessment on an older adult, the nurse notices a number of irregular round brownish-colored lesions on the client’s hands, arms, and face. On palpation, they are flat and slightly rough to the touch. Based on this assessment finding, which action should the nurse implement?
- A. Apply a topical antibiotic ointment.
- B. Monitor the lesions for changes.
- C. Advise the client to use sunscreen.
- D. Refer the client for a skin lesion biopsy.
Correct answer: D
Rationale: Referral for a skin biopsy is necessary to rule out potential malignancy of irregular skin lesions. Applying a topical antibiotic ointment (Choice A) is not indicated for irregular pigmented lesions. Monitoring the lesions for changes (Choice B) may delay appropriate intervention if malignancy is present. Advising the client to use sunscreen (Choice C) is important for sun protection but is not the priority when irregular lesions are present.
5. A client with chronic heart failure is experiencing dyspnea and has an oxygen saturation of 88%. Which position is most appropriate to improve oxygenation?
- A. Supine with legs elevated
- B. High Fowler's position
- C. Prone with pillows under the chest
- D. Side-lying with head flat
Correct answer: B
Rationale: The correct answer is B: High Fowler's position. High Fowler's position is the most appropriate for a client with chronic heart failure experiencing dyspnea and low oxygen saturation. This position helps improve lung expansion and oxygenation by maximizing chest expansion and allowing better ventilation. Choice A, supine with legs elevated, may worsen dyspnea by reducing lung expansion. Choice C, prone with pillows under the chest, is not suitable for a client experiencing dyspnea as it may further compromise breathing. Choice D, side-lying with head flat, does not facilitate optimal lung expansion and is not the best choice for improving oxygenation in this scenario.
