1. 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.

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. The healthcare provider notes a blood pressure of 160/90 mm Hg in a patient taking a thiazide diuretic. The patient reports taking an herbal medication that a friend recommended. Which herbal product is likely, given this patient’s blood pressure?

• A. Ginkgo
• B. Hawthorn
• C. Licorice
• D. St. John’s wort

Correct answer: A

Rationale: The correct answer is A: Ginkgo. Increased blood pressure can result when ginkgo is used in combination with a thiazide diuretic. Option B (Hawthorn) is incorrect because hawthorn is more commonly associated with lowering blood pressure. Option C (Licorice) is incorrect because licorice can lead to sodium and water retention, potentially exacerbating hypertension. Option D (St. John’s wort) is incorrect as it is not typically associated with significant blood pressure effects.

4. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:

• A. Compensated metabolic acidosis
• B. Compensated respiratory alkalosis
• C. Uncompensated metabolic alkalosis
• D. Uncompensated respiratory acidosis

Correct answer: B

Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.

5. The nurse is providing discharge teaching for a patient who will receive oral levofloxacin (Levaquin) to treat pneumonia. The patient takes an oral hypoglycemic medication and uses over-the-counter (OTC) antacids to treat occasional heartburn. The patient reports frequent arthritis pain and takes acetaminophen when needed. Which statement by the nurse is correct when teaching this patient?

• A. You may take antacids with levofloxacin to decrease gastrointestinal upset.
• B. You may take nonsteroidal anti-inflammatory medications (NSAIDs) for arthritis pain.
• C. You should monitor your serum glucose more closely while taking levofloxacin.
• D. You should take levofloxacin on an empty stomach to improve absorption.

Correct answer: C

Rationale: Levofloxacin may increase the effects of oral hypoglycemic medications, so patients taking these should be advised to monitor their serum glucose levels closely.
