1. The client is being educated by the nurse on home blood glucose monitoring. Which of the following blood glucose measurements indicates hypoglycemia?
- A. 59 mg/dL (3.3 mmol/L)
- B. 75 mg/dL (4.2 mmol/L)
- C. 108 mg/dL (6 mmol/L)
- D. 119 mg/dL (6.6 mmol/L)
Correct answer: A
Rationale: A blood glucose level of 59 mg/dL (3.3 mmol/L) is considered hypoglycemia, which is an abnormally low blood sugar level. This level requires immediate attention as it can lead to symptoms such as confusion, shakiness, and even loss of consciousness if left untreated. Choices B, C, and D have blood glucose levels within the normal range or slightly higher, indicating euglycemia or normal blood sugar levels, and not hypoglycemia.
2. The patient is taking low-dose erythromycin prophylactically and will start cefaclor for treating an acute infection. The nurse should discuss this with the provider because taking both medications simultaneously can cause which effect?
- A. Decreased effectiveness of cefaclor.
- B. Increased effectiveness of cefaclor.
- C. Decreased effectiveness of erythromycin.
- D. Increased effectiveness of erythromycin.
Correct answer: A
Rationale: When erythromycin and cefaclor are taken together, erythromycin can inhibit the metabolism of cefaclor, leading to elevated cefaclor levels and potentially causing adverse effects. This results in a decrease in the effectiveness of cefaclor. Therefore, the nurse should discuss this potential drug interaction with the provider to consider an alternative treatment or adjust the dosages to prevent complications. Choices B, C, and D are incorrect because the concern lies with the effect on cefaclor when combined with erythromycin, not the effect on erythromycin itself.
3. A patient with a diagnosis of Cushing's syndrome is likely to exhibit which of the following symptoms?
- A. Hyperpigmentation.
- B. Moon face.
- C. Hypotension.
- D. Hypertension.
Correct answer: B
Rationale: The correct answer is B: Moon face. Cushing's syndrome is characterized by excess cortisol levels, leading to the distinctive round and full face known as moon face. Hyperpigmentation (choice A) may occur due to increased ACTH levels, but it is not a hallmark symptom like moon face. Hypotension (choice C) is less common in Cushing's syndrome as cortisol typically leads to hypertension (choice D) due to its effects on blood pressure regulation.
4. Which of the following interventions is most appropriate for a patient with left-sided heart failure?
- A. Administering IV fluids.
- B. Administering oxygen.
- C. Administering diuretics.
- D. Administering antihypertensives.
Correct answer: B
Rationale: Administering oxygen is the most appropriate intervention for a patient with left-sided heart failure because it helps improve oxygenation. In left-sided heart failure, the heart struggles to pump oxygen-rich blood to the body, leading to inadequate oxygen supply to tissues. Administering oxygen can help alleviate symptoms of hypoxia and reduce the workload on the heart. IV fluids (Choice A) may exacerbate heart failure by increasing fluid volume, diuretics (Choice C) are used to reduce fluid overload in heart failure, and antihypertensives (Choice D) are more suitable for managing hypertension, which may be a comorbidity in heart failure but are not the primary intervention for left-sided heart failure.
5. The patient is being educated on taking hydrochlorothiazide. Which statement by the patient indicates a need for further teaching?
- A. I may need additional sodium and calcium while taking this medication.
- B. I should consume plenty of fruits and vegetables while taking this drug.
- C. I should be cautious when getting up from a bed or chair while on this medication.
- D. I will take the medication in the morning to reduce certain side effects.
Correct answer: A
Rationale: The correct answer is A because patients do not require extra sodium or calcium while taking hydrochlorothiazide, a thiazide diuretic. This medication actually promotes the excretion of sodium and water. Choices B, C, and D are correct statements regarding the use of hydrochlorothiazide. Patients are encouraged to have a diet rich in fruits and vegetables, be careful with position changes due to potential orthostatic hypotension, and take the medication in the morning to reduce the need for frequent urination during nighttime.
