1. A client with a history of heart failure is admitted with severe dyspnea. Which laboratory result requires immediate intervention?
- A. Blood glucose of 150 mg/dL.
- B. Serum potassium of 3.5 mEq/L.
- C. Serum creatinine of 1.0 mg/dL.
- D. Blood urea nitrogen (BUN) of 20 mg/dL.
Correct answer: C
Rationale: The correct answer is C. A serum creatinine level of 1.0 mg/dL is within the normal range. However, in a client with heart failure and severe dyspnea, fluid retention is a significant concern. An elevated serum creatinine level may indicate impaired kidney function, which can worsen fluid overload. Therefore, immediate intervention is required to prevent further complications. Choices A, B, and D are within normal ranges and not indicative of immediate intervention in this scenario.
2. In a community clinic where a recent case of tuberculosis (TB) has been diagnosed, which client who attended the clinic is at the highest risk for presenting with TB?
- A. a young adult who works as a daycare worker
- B. an adult who works in a corporate office
- C. an adolescent who attends the community high school
- D. an adult with a history of alcoholism and homelessness
Correct answer: D
Rationale: Individuals who are homeless and have a history of alcoholism are at the highest risk for presenting with TB in this scenario. Homeless individuals often live in crowded conditions with poor ventilation, increasing the likelihood of TB transmission. Additionally, alcoholism can weaken the immune system, making individuals more susceptible to developing TB. The other options, such as a daycare worker, an office worker, or a high school student, do not inherently carry the same level of risk factors for TB transmission as being homeless with a history of alcoholism.
3. A client with Diabetes Insipidus (DI) is being cared for by a nurse. Which data warrants the most immediate intervention by the nurse?
- A. Serum sodium of 185 mEq/L (185 mmol/L)
- B. Dry skin with poor skin turgor
- C. Apical rate of 110 beats per minute
- D. Polyuria and excessive thirst
Correct answer: A
Rationale: A serum sodium level of 185 mEq/L (185 mmol/L) is dangerously high and indicates severe dehydration, requiring immediate intervention to prevent neurological damage. The other options are not as critical as high serum sodium levels, which can lead to serious complications such as seizures, coma, and death if not promptly addressed. Dry skin with poor skin turgor and polyuria with excessive thirst are common findings in clients with Diabetes Insipidus and should be managed but do not pose an immediate threat to the client's life. An apical heart rate of 110 beats per minute may indicate tachycardia, which could be related to dehydration but is not as urgent as addressing the severe hypernatremia.
4. A client is receiving morphine sulfate subcutaneously for pain. Because morphine sulfate has been prescribed for this client, which nursing action would be included in the plan of care?
- A. Encourage fluid intake.
- B. Monitor the client's temperature.
- C. Maintain the client in a supine position.
- D. Encourage the client to cough and deep breathe.
Correct answer: D
Rationale: Morphine sulfate suppresses the cough reflex, which can lead to the retention of secretions in the lungs. Encouraging the client to cough and deep breathe helps prevent pneumonia by clearing the airways of any accumulated secretions. This intervention is crucial in clients receiving morphine sulfate to maintain optimal respiratory function.
5. The nurse is caring for a patient who will receive 10% calcium gluconate to treat a serum potassium level of 5.9 mEq/L. The nurse performs a drug history prior to beginning the infusion. Which drug taken by the patient would cause concern?
- A. Digitalis
- B. Hydrochlorothiazide
- C. Hydrocortisone
- D. Vitamin D
Correct answer: A
Rationale: Calcium gluconate is administered to treat hyperkalemia by reducing myocardial irritability. When given to a patient taking digitalis, it can lead to digitalis toxicity. Digitalis and calcium gluconate both affect cardiac function, and their concomitant use can potentiate adverse effects. Hydrochlorothiazide, Hydrocortisone, and Vitamin D may impact potassium levels, but they do not interact with calcium gluconate in a way that would cause concern for toxicity.
