1. The nurse is providing care for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which laboratory result requires immediate intervention?
- A. Serum sodium of 140 mEq/L.
- B. Serum potassium of 4.5 mEq/L.
- C. Serum osmolality of 280 mOsm/kg.
- D. Serum sodium of 130 mEq/L.
Correct answer: D
Rationale: The correct answer is D: Serum sodium of 130 mEq/L. In SIADH, there is excess release of antidiuretic hormone leading to water retention and dilutional hyponatremia. A serum sodium level of 130 mEq/L indicates severe hyponatremia, which can result in neurological symptoms, such as confusion, seizures, and coma. Therefore, immediate intervention is required to prevent further complications. Choice A, a serum sodium of 140 mEq/L, is within the normal range and does not require immediate intervention. Choice B, serum potassium of 4.5 mEq/L, is also within the normal range and is not directly related to SIADH. Choice C, serum osmolality of 280 mOsm/kg, is a measure of the concentration of solutes in the blood and may not be the most critical parameter to address in a client with SIADH and severe hyponatremia.
2. A client with a history of chronic kidney disease (CKD) is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?
- A. Serum potassium level
- B. White blood cell count
- C. Hemoglobin level
- D. Serum calcium level
Correct answer: A
Rationale: The correct answer is A: Serum potassium level. In a client receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increased demand for potassium. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because erythropoietin therapy specifically impacts potassium levels, not white blood cell count, hemoglobin level, or serum calcium level.
3. A client with deep vein thrombosis (DVT) is receiving heparin and reports tarry stools. What should the nurse do?
- A. Prepare to administer warfarin.
- B. Assess characteristics of the client's pain.
- C. Monitor stools for blood and review PTT results.
- D. Continue the heparin and prepare to administer Vitamin K.
Correct answer: C
Rationale: When a client on heparin reports tarry stools, it can be indicative of gastrointestinal bleeding. The correct action for the nurse is to monitor the stools for blood and review the Partial Thromboplastin Time (PTT) results. This is essential to detect any potential bleeding complications associated with heparin therapy. Option A is incorrect because warfarin is not the immediate intervention for tarry stools in a client on heparin. Option B is irrelevant to the situation described. Option D is incorrect as Vitamin K is the antidote for warfarin, not heparin.
4. The daughter of an older woman who became depressed following the death of her husband asks, 'My mother was always well-adjusted until my father died. Will she tend to be sick from now on?' Which response is best for the nurse to provide?
- A. She is almost sure to be less able to adapt than before.
- B. It's highly likely that she will recover and return to her pre-illness state.
- C. If you can interest her in something besides religion, it will help her stay well.
- D. Cultural strains contribute to each woman's tendencies for recurrences of depression.
Correct answer: B
Rationale: The successful resolution of a developmental crisis in the later years involves acceptance and adaptation, and the daughter should be reassured that recovery is likely.
5. When is the first dose of Hepatitis B vaccine typically administered?
- A. In the hospital at birth
- B. At one year old
- C. At six months
- D. At 18 months
Correct answer: A
Rationale: The first dose of the Hepatitis B vaccine is usually administered at birth in the hospital to provide early protection against the virus. Giving the vaccine at birth helps prevent perinatal transmission of Hepatitis B from an infected mother to her newborn. This early administration is crucial in establishing immunity in infants, as delaying the vaccine increases the risk of infection. Options B, C, and D are incorrect because delaying the administration of the Hepatitis B vaccine can leave infants vulnerable to the virus during the critical early months of life when they are most susceptible.
