Nursing Elites

1. In a client with congestive heart failure, the nurse would be correct in withholding a dose of digoxin without specific instruction from the healthcare provider if the client's

• A. serum digoxin level is 1.5 ng/mL.
• B. blood pressure is 104/68 mmHg.
• C. serum potassium level is 3 mEq/L.
• D. apical pulse is 68/min.

Correct answer: C

Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.

2. In a patient with diabetes, which of the following is a sign of hypoglycemia?

• A. Polydipsia
• B. Polyuria
• C. Dry skin
• D. Sweating

Correct answer: D

Rationale: Sweating is a common sign of hypoglycemia in patients with diabetes. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, leading to symptoms such as sweating, shakiness, and palpitations. Polydipsia (excessive thirst) and polyuria (excessive urination) are more commonly associated with hyperglycemia (high blood sugar levels) in diabetes. Dry skin is not a typical symptom of hypoglycemia.

3. A client with chronic kidney disease starts on hemodialysis. During the first dialysis treatment, the client's blood pressure drops from 150/90 to 80/30. Which action should the nurse take first?

• A. Stop the dialysis treatment
• B. Administer 5% albumin IV
• C. Monitor blood pressure every 45 minutes
• D. Lower the head of the chair and elevate feet

Correct answer: D

Rationale: The initial action the nurse should take when a client's blood pressure drops significantly during hemodialysis is to lower the head of the chair and elevate the feet. This position adjustment helps improve blood flow to the brain and vital organs, assisting in stabilizing blood pressure. Stopping the dialysis treatment immediately may not be necessary if the blood pressure can be managed effectively by position changes. Administering 5% albumin IV is not the first-line intervention for hypotension during dialysis. Monitoring blood pressure every 45 minutes is important but not the immediate action needed to address the significant drop in blood pressure observed during the dialysis session.

4. What is the most common symptom of hypoglycemia that the nurse should teach the diabetic client to recognize?

• A. Nervousness
• B. Anorexia
• C. Kussmaul's respirations
• D. Bradycardia

Correct answer: A

Rationale: Nervousness is the most common symptom of hypoglycemia. It is often accompanied by other signs such as weakness, perspiration, confusion, and palpitations. Anorexia (lack of appetite) is not a typical symptom of hypoglycemia; it is more commonly associated with hyperglycemia. Kussmaul's respirations are a deep and labored breathing pattern seen in diabetic ketoacidosis, not hypoglycemia. Bradycardia (slow heart rate) is not a typical symptom of hypoglycemia; tachycardia (fast heart rate) is more commonly associated with hypoglycemia due to the release of catecholamines in response to low blood sugar.

5. In assessing cancer risk, which woman is at greatest risk of developing breast cancer?

• A. A 35-year-old multipara who never breastfed.
• B. A 50-year-old whose mother had unilateral breast cancer.
• C. A 55-year-old whose mother-in-law had bilateral breast cancer.
• D. A 20-year-old whose menarche occurred at age 9.

Correct answer: B

Rationale: The correct answer is B because family history of breast cancer, specifically in the mother, is a significant risk factor for developing breast cancer. The age of 50 is also a risk factor for breast cancer. Choice A is less likely as breastfeeding can actually reduce the risk of breast cancer. Choice C is less relevant since the risk is higher with a direct family member. Choice D, although early menarche is a risk factor, the age of the individual is much lower compared to the other age-related risk factors.
