Nursing Elites

1. A client is brought to the emergency department by a neighbor. The client is lethargic and has a fruity odor on the breath. The client’s arterial blood gas (ABG) results are pH 7.25, PCO2 34 mm Hg, PO2 86 mm Hg, HCO3 14 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: The correct answer is 'Metabolic acidosis.' Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (HCO3 <22 mEq/L). In this case, the client's ABG results show a pH of 7.25 and an HCO3 level of 14 mEq/L, indicating metabolic acidosis. The PCO2 of 34 mm Hg is normal, ruling out respiratory acidosis or alkalosis. The PO2 of 86 mm Hg is also within the normal range and is not indicative of a respiratory problem. Therefore, the client is experiencing metabolic acidosis based on the ABG results provided.

2. While assisting a client with a closed chest tube drainage system to move from bed to a chair, the chest tube gets caught on the chair leg and becomes dislodged from the insertion site. What is the immediate priority for the nurse?

• A. Contacting the physician
• B. Reinserting the chest tube
• C. Transferring the client back to bed
• D. Covering the insertion site with a sterile occlusive dressing

Correct answer: D

Rationale: The immediate priority for the nurse when a chest tube becomes dislodged from the insertion site is to cover the site with a sterile occlusive dressing. This action helps prevent air from entering the pleural space, which could lead to a pneumothorax. The nurse should then perform a respiratory assessment to monitor the client's breathing, assist the client back into bed to a position of comfort, and notify the physician. Reinserting the chest tube is a task for the physician, not the nurse, as it requires specific training and expertise.

3. Which of the following lab values would be most concerning in a patient receiving heparin therapy?

• A. Elevated hemoglobin levels.
• B. Low platelet count.
• C. High potassium levels.
• D. Low sodium levels.

Correct answer: B

Rationale: A low platelet count is most concerning in patients receiving heparin therapy due to the risk of heparin-induced thrombocytopenia. Heparin can sometimes cause a drop in platelet count, leading to a potentially serious condition where blood does not clot as it should. This can result in excessive bleeding or clot formation in blood vessels. Elevated hemoglobin levels, high potassium levels, and low sodium levels are not typically associated with heparin therapy and are less likely to cause immediate concerns or complications in this context.

4. An elderly client is admitted with a diagnosis of bacterial pneumonia. The nurse's assessment of the client will most likely reveal which sign/symptom?

• A. Leukocytosis and febrile.
• B. Polycythemia and crackles.
• C. Pharyngitis and sputum production.
• D. Confusion and tachycardia.

Correct answer: D

Rationale: The onset of pneumonia in the elderly may be signaled by general deterioration, confusion, increased heart rate or increased respiratory rate due to the decreased oxygen- carbon dioxide exchange at the alveoli, known as the V-Q mismatch.

5. A middle-aged male client with diabetes continues to eat an abundance of foods that are high in sugar and fat. According to the Health Belief Model, which event is most likely to increase the client's willingness to become compliant with the prescribed diet?

• A. He visits his diabetic brother who just had surgery to amputate an infected foot.
• B. He is provided with the most current information about the dangers of untreated diabetes.
• C. He comments on the community service announcements about preventing complications associated with diabetes.
• D. His wife expresses a sincere willingness to prepare meals that are within his prescribed diet.

Correct answer: A

Rationale: According to the Health Belief Model, the most effective event to increase compliance with the prescribed diet for a middle-aged male client with diabetes is experiencing a significant consequence related to the disease. In this case, visiting his diabetic brother who just had surgery to amputate an infected foot would serve as a strong 'cue to action,' increasing the client's perceived seriousness of the disease. This event is likely to have a more immediate and impactful effect on the client than other options. Option B provides valuable information but may not have the same personal and emotional impact as witnessing a severe consequence firsthand. Option C involves indirect exposure to prevention messages, which might not be as compelling as a direct experience. Option D, while supportive, does not present a direct consequence of non-compliance like option A does.
