Nursing Elites

1. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?

• A. metabolic alkalosis
• B. homeostasis
• C. respiratory acidosis
• D. respiratory alkalosis

Correct answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within the normal range, indicating a state of balance and homeostasis. The pH is within the normal range (7.35-7.45), the PCO2 is normal (35-45 mmHg), and the HCO3 level is also normal (22-26 mEq/L). Choice A, 'metabolic alkalosis,' is incorrect because the pH, PCO2, and HCO3 levels are not indicative of metabolic alkalosis. Choice C, 'respiratory acidosis,' is incorrect as the pH and PCO2 values are not elevated. Choice D, 'respiratory alkalosis,' is incorrect as the pH and PCO2 levels are not decreased. Therefore, the ABG values provided do not correspond to any acid-base disturbance, confirming that the patient is in a state of homeostasis.

2. A physician orders a serum creatinine for a hospitalized client. The nurse should explain to the client and his family that this test:

• A. is normal if the level is 4.0 to 5.5 mg/dl.
• B. can be elevated with increased protein intake.
• C. is a better indicator of renal function than the BUN.
• D. reflects the fluid volume status of a person

Correct answer: C

Rationale: A serum creatinine level should be 0.7 to 1.5 mg/dl, and it does not vary with increased protein intake, so it is a better indicator of renal function than the BUN. Choice A is incorrect as a serum creatinine level of 4.0 to 5.5 mg/dl is not normal. Choice B is incorrect as serum creatinine is not affected by increased protein intake. Choice D is incorrect as serum creatinine primarily reflects renal function, not fluid volume status.

3. Clomiphene is prescribed for a female client to treat infertility. The nurse is providing information to the client and her spouse about the medication and provides the couple with which information?

• A. If the oral tablets are not successful, the medication will be administered intravenously.
• B. The couple should engage in coitus at least every other day during treatment.
• C. The physician should be notified immediately if breast engorgement occurs.
• D. Multiple births occur in a small percentage of clomiphene-facilitated pregnancies.

Correct answer: D

Rationale: The correct answer is that multiple births (usually twins) occur in a small percentage (8% - 10%) of clomiphene-facilitated pregnancies. The couple should be informed about this potential outcome. Clomiphene is available in 50-mg tablets for oral use; there is no intravenous form of the medication. Breast engorgement is a common side effect of clomiphene that typically resolves after discontinuation of the medication. Ovulation usually happens 5 to 10 days after the last dose of clomiphene, and the couple is advised to engage in coitus at least every other day during this time. Therefore, choices A, B, and C are incorrect as they do not provide accurate information regarding clomiphene treatment for infertility.

4. The drug of choice to decrease uric acid levels is:

• A. prednisone (Colisone)
• B. allopurinol (Zyloprim)
• C. indomethacin (Indocin)
• D. hydrochlorothiazide (HydroDiuril)

Correct answer: B

Rationale: The correct answer is allopurinol (Zyloprim) as it is a xanthine oxidase inhibitor that decreases uric acid formation. Allopurinol is commonly used to manage gout by lowering uric acid levels. Prednisone is a corticosteroid used to decrease inflammation, not to lower uric acid levels. Indomethacin is an analgesic, anti-inflammatory, and antipyretic agent, but it is not the drug of choice for lowering uric acid levels. Hydrochlorothiazide is a thiazide diuretic used to treat hypertension and edema, not to decrease uric acid levels.

5. When teaching a patient with COPD pulmonary exercises, what should be done?

• A. Teach pursed-lip breathing techniques.
• B. Encourage repetitive heavy lifting exercises to increase strength.
• C. Limit exercises due to respiratory acidosis.
• D. Take breaks every 10-20 minutes during exercises.

Correct answer: A

Rationale: The correct answer is to teach pursed-lip breathing techniques. Pursed-lip breathing helps to decrease the volume of air expelled by keeping the airways open longer, making it easier for patients with COPD to breathe out. Encouraging heavy lifting exercises (Choice B) is not suitable for patients with COPD as it can lead to increased shortness of breath. Limiting exercises due to respiratory acidosis (Choice C) is not correct; instead, exercises should be tailored to the patient's tolerance. Taking breaks every 10-20 minutes (Choice D) is not specific to the management of COPD pulmonary exercises.
