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. Which of the following is a key symptom of hypothyroidism?

• A. Weight loss.
• B. Heat intolerance.
• C. Cold intolerance.
• D. Increased appetite.

Correct answer: C

Rationale: Cold intolerance is a key symptom of hypothyroidism because a decreased metabolic rate leads to a reduced ability to regulate body temperature. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism, where excess thyroid hormone leads to an increased sensitivity to heat. Increased appetite (Choice D) is not typically seen in hypothyroidism; instead, individuals with hypothyroidism may experience weight gain due to the slowed metabolism.

3. A client is getting out of bed for the first time since surgery. The client complains of dizziness after the nurse raises the head of the bed. Which of the following actions should the nurse take first?

• A. Checking the client’s blood pressure
• B. Checking the oxygen saturation level
• C. Having the client take some deep breaths
• D. Lowering the head of the bed slowly until the dizziness is relieved

Correct answer: D

Rationale: When a client experiences dizziness after being positioned upright for the first time post-surgery, the initial action the nurse should take is to lower the head of the bed slowly until the dizziness subsides. This maneuver helps alleviate the dizziness by allowing the body to adapt gradually to the change in position. Subsequently, the nurse should assess the client's pulse and blood pressure. Checking the blood pressure is essential to evaluate the circulatory status and rule out orthostatic hypotension as a cause of dizziness. Checking the oxygen saturation level and having the client take deep breaths are not the priority in this scenario as the primary concern is addressing the circulatory issue causing dizziness, not a respiratory problem.

4. A client with histoplasmosis has the following arterial blood gas (ABG) results: pH 7.30, PCO2 58 mm Hg, PO2 75 mm Hg, HCO3 27 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 client's ABG results show a low pH (acidosis) and an elevated PCO2, indicating respiratory acidosis. In respiratory acidosis, there is inadequate excretion of CO2, leading to increased PCO2 levels and a decrease in pH. Therefore, the correct answer is 'Metabolic acidosis'. Choices B, C, and D are incorrect. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory acidosis involves low pH and high PCO2 levels, as seen in this case. Respiratory alkalosis is associated with high pH and low PCO2 levels.

5. A client with a family history of polycystic kidney disease (PKD is being assessed by a nurse. For which clinical manifestations should the nurse assess? (Select all that apply.)

• A. Nocturia
• B. Flank pain
• C. Increased abdominal girth
• D. B & C

Correct answer: D

Rationale: Clients with PKD commonly present with flank pain and increased abdominal girth due to abdominal distention caused by cysts. Bloody urine is also a common symptom due to tissue damage from PKD. Nocturia and dysuria are not typical manifestations of PKD. Constipation is not directly associated with PKD. Therefore, the correct choices are flank pain and increased abdominal girth, making option D the correct answer.
