Nursing Elites

1. While suctioning the endotracheal tube of an adult client, what level of pressure should the nurse apply?

• A. 70-80 mmHg
• B. 100-120 mmHg
• C. 150-170 mmHg
• D. 200 mmHg

Correct answer: B

Rationale: When suctioning the endotracheal tube of an adult client, the nurse should set the suction apparatus at a level no higher than 150 mmHg, with a preferable level between 100 and 120 mmHg. Suction pressure that is too high can contribute to the client's hypoxia. Alternatively, too low suction pressure may not clear adequate amounts of secretions. Choice A (70-80 mmHg) is too low and may not effectively clear secretions. Choices C (150-170 mmHg) and D (200 mmHg) are too high and can potentially harm the client by causing hypoxia or damaging the airway.

2. A client complained of nausea, a metallic taste in her mouth, and fine hand tremors 2 hours after her first dose of lithium carbonate (Lithane). What is the nurse's best explanation of these findings?

• A. These side effects are common and should subside in a few days.
• B. The client is probably having an allergic reaction and should discontinue the drug.
• C. Taking the lithium on an empty stomach should decrease these symptoms.
• D. Decreasing dietary intake of sodium and fluids should minimize the side effects.

Correct answer: A

Rationale: The correct answer is, 'These side effects are common and should subside in a few days.' Nausea, metallic taste, and fine hand tremors are common side effects of lithium carbonate (Lithane) and typically diminish within a few days as the body adjusts to the medication. Option B is incorrect because these symptoms are not indicative of an allergic reaction. Option C is incorrect as taking lithium on an empty stomach does not directly address or decrease these specific side effects. Option D is also incorrect as reducing sodium and fluid intake is not the recommended approach to managing these particular side effects of lithium.

3. Which of the following is NOT a warning sign that compensatory mechanisms in a patient in shock are failing?

• A. Increasing heart rate above normal for the patient's age.
• B. Absent peripheral pulses
• C. Decreasing level of consciousness
• D. Increasing blood pressure

Correct answer: D

Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.

4. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

• A. Start an IV so contrast media may be given
• B. Ensure that the patient has been NPO for at least 6 hours.
• C. Inform radiology that a radioactive glucose preparation is needed
• D. Instruct the patient to undress to the waist and remove any metal objects

Correct answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

5. While receiving normal saline infusions to treat a GI bleed, the nurse notes that the patient's lower legs have become edematous and auscultates crackles in the lungs. What should the nurse do first?

• A. Stop the saline infusion immediately
• B. Notify the physician
• C. Elevate the patient's legs
• D. Continue the infusion, as these findings are normal

Correct answer: A

Rationale: The correct answer is to stop the saline infusion immediately. The patient is showing signs of fluid volume overload due to rapid fluid replacement, indicated by lower leg edema and lung crackles. Continuing the infusion could worsen the overload and potentially lead to complications. Notifying the physician is important but should come after stopping the infusion to address the immediate issue. Elevating the patient's legs may help with edema but is not the priority in this situation. Continuing the infusion when the patient is already showing signs of fluid overload is contraindicated and can be harmful.
