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. A CD4+ lymphocyte count is performed on a client infected with HIV. The results of the test indicate a CD4+ count of 450 cells/L. The nurse interprets this test result as indicating:
- A. Improvement in the client
- B. The need for antiretroviral therapy
- C. The need to discontinue antiretroviral therapy
- D. An effective response to the treatment for HIV
Correct answer: B
Rationale: A CD4+ count of 450 cells/L is below the normal range (500-1600 cells/mcL), indicating a decline in immune function in the client. Antiretroviral therapy is recommended when the CD4+ count falls below 500 cells/mcL or below 25%, or when the client displays symptoms of HIV. Therefore, the interpretation of this test result suggests that the client requires antiretroviral therapy to manage the HIV infection. Choices A, C, and D are incorrect because a CD4+ count of 450 cells/L does not signify improvement, discontinuation of therapy, or an effective response to treatment for HIV.
3. A nurse is assessing a postoperative client on an hourly basis. The nurse notes that the client’s urine output for the past hour was 25 mL. Based on this finding, the nurse first:
- A. Calls the physician
- B. Increases the rate of the IV infusion
- C. Checks the client’s overall intake and output record
- D. Administers a 250-mL bolus of normal saline solution (0.9%)
Correct answer: C
Rationale: Clients are at risk of hypovolemia postoperatively, and decreased urine output can be an early sign. However, to accurately interpret this finding, the nurse must assess the overall fluid balance by checking the client’s intake and output records. Increasing the IV infusion rate or administering a bolus of normal saline solution without a physician's order would not be appropriate as these interventions require a prescription. The physician should be notified once the nurse has collected all necessary assessment data, including fluid status and vital signs.
4. A 20-year-old female client calls the nurse to report a lump she found in her breast. Which response is the best for the nurse to provide?
- A. Check it again in one month, and if it is still there schedule an appointment.
- B. Most lumps are benign, but it is always best to come in for an examination.
- C. Try not to worry too much about it, because usually, most lumps are benign.
- D. If you are in your menstrual period it is not a good time to check for lumps.
Correct answer: B
Rationale: The nurse advising the client to come in provides the best response because it addresses the client's anxiety most effectively and encourages prompt and immediate action for a potential problem.
5. After teaching a client with renal cancer who is prescribed temsirolimus (Torisel), the nurse assesses the client’s understanding. Which statement made by the client indicates a correct understanding of the teaching?
- A. I will take this medication with food and plenty of water.
- B. I shall keep my appointment at the infusion center each week.
- C. I’ll limit my intake of green leafy vegetables while on this medication.
- D. I must not take this medication if I have an infection or am feeling ill.
Correct answer: B
Rationale: The correct answer is B. Temsirolimus, also known as Torisel, is administered as a weekly intravenous infusion. This medication blocks protein needed for cell division, inhibiting cell cycle progression. It is not taken orally, so there is no need to take it with food or water. Keeping the weekly infusion center appointment is crucial for the client to receive the prescribed treatment effectively. Choice A is incorrect as temsirolimus is not taken with food or water. Choice C is incorrect because there is no need to limit the intake of green leafy vegetables while on this medication. Choice D is incorrect as having an infection or feeling ill does not prohibit the use of temsirolimus.
