Nursing Elites

1. A nurse is reviewing the ABG results of a client with chronic emphysema. Which result suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A PaCO2 level of 55 mm Hg is elevated, indicating carbon dioxide retention, a common complication of emphysema that necessitates intervention. Elevated PaCO2 can lead to respiratory acidosis, reflecting inadequate ventilation. Choices A, C, and D are within normal ranges. A PaO2 level of 89 mm Hg is acceptable. An HCO3 level of 25 mEq/L falls within the normal range, suggesting adequate compensation. A pH level of 7.37 is also within the normal range, indicating the client's acid-base balance is maintained.

2. When providing education on the use of insulin, what should be included?

• A. Insulin can be stored at room temperature indefinitely
• B. Monitor blood glucose levels before administration
• C. Insulin is a long-acting medication
• D. Insulin has no side effects

Correct answer: B

Rationale: The correct answer is to monitor blood glucose levels before administration. This step is crucial to ensure the correct dose of insulin is administered based on the current blood glucose level. Choice A is incorrect as insulin usually needs to be stored in the refrigerator and has an expiration date. Choice C is incorrect because insulin can be short-acting, rapid-acting, intermediate-acting, or long-acting. Choice D is also incorrect as insulin can have side effects such as hypoglycemia if the dose is too high.

3. Before an amniocentesis, what action by the client will need to be completed?

• A. Increase fluid intake
• B. Empty the bladder
• C. Avoid eating for 12 hours
• D. Take a sedative

Correct answer: B

Rationale: Before an amniocentesis, the client should empty their bladder. This is necessary to reduce the risk of bladder puncture during the procedure. A full bladder can be in the path of the needle, increasing the risk of injury. Increasing fluid intake (choice A) is not necessary before an amniocentesis. Avoiding eating for 12 hours (choice C) is not a standard preparation for an amniocentesis. Taking a sedative (choice D) is not routinely required for this procedure.

4. A client with heart failure who presents with dyspnea, bibasilar crackles, and frothy sputum should receive which dietary recommendation?

• A. Decrease protein intake.
• B. Reduce sodium intake.
• C. Increase fluid intake.
• D. Decrease calcium intake.

Correct answer: B

Rationale: The correct answer is to reduce sodium intake. In heart failure, excess sodium can lead to fluid retention, exacerbating symptoms like dyspnea, bibasilar crackles, and frothy sputum. Therefore, reducing sodium intake is crucial in managing heart failure. Decreasing protein intake is not typically recommended in heart failure management. Increasing fluid intake would worsen the condition by further contributing to fluid overload. Decreasing calcium intake is not directly related to managing heart failure symptoms such as dyspnea, bibasilar crackles, and frothy sputum.

5. A healthcare professional is assessing a client for signs of dehydration. Which of the following findings should the healthcare professional look for?

• A. Edema
• B. Dry mucous membranes
• C. Weight gain
• D. Increased urination

Correct answer: B

Rationale: Dry mucous membranes are a classic sign of dehydration. In dehydration, the body loses more water than it takes in, leading to dryness of mucous membranes like the mouth and throat. Edema (choice A) is swelling caused by excess fluid trapped in the body's tissues, which is not a typical sign of dehydration. Weight gain (choice C) is also not a common sign of dehydration; in fact, dehydration usually leads to weight loss. Increased urination (choice D) is more indicative of conditions like diabetes or diuretic use, not dehydration.
