Nursing Elites

1. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?

• A. To promote oxygenation by removing secretions.
• B. To reduce the amount of air trapped in the lungs.
• C. To increase the amount of carbon dioxide exhaled.
• D. To slow the respiratory rate and improve air exchange.

Correct answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.

2. During the digital removal of a fecal impaction, the nurse should stop the procedure and take corrective action if which client reaction is noted?

• A. Temperature increases from 98.8° to 99.0° F.
• B. Pulse rate decreases from 78 to 52 beats/min.
• C. Respiratory rate increases from 16 to 24 breaths/min.
• D. Blood pressure increases from 110/84 to 118/88 mmHg.

Correct answer: B

Rationale: During digital removal of a fecal impaction, a vagal response can occur due to stimulation of the anal sphincter. If the client experiences bradycardia (pulse rate decreases), the nurse should stop the procedure immediately and take corrective action to prevent any complications. Choices A, C, and D are incorrect because they do not indicate a vagal response, which is the expected adverse reaction during this procedure.

3. The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?

• A. The client will experience increased tolerance to the drug's effects and may need a higher dose.
• B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect.
• C. The medication will be more highly protein-bound, increasing the duration of action.
• D. The therapeutic index will be increased, placing the client at greater risk for toxicity.

Correct answer: B

Rationale: When a medication is administered via the IV route, the absorptive process is bypassed, leading to a more rapid onset of action. This results in a faster effect of the drug. Choice A is incorrect because changing the route of administration does not necessarily lead to increased tolerance or the need for a higher dose. Choice C is incorrect as changing the route of administration does not directly affect the protein binding of a medication. Choice D is incorrect because increasing the therapeutic index would actually reduce the risk of toxicity, not increase it.

4. A client has a nursing diagnosis of Altered sleep patterns related to nocturia. Which client instruction is important for the nurse to provide?

• A. Decrease intake of fluids after the evening meal.
• B. Drink a glass of cranberry juice every day.
• C. Drink a glass of warm decaffeinated beverage at bedtime.
• D. Consult the healthcare provider about a sleeping pill.

Correct answer: A

Rationale: The correct instruction for the nurse to provide is to advise the client to decrease intake of fluids after the evening meal. By reducing fluid intake before bedtime, the client can minimize the need to void during the night, which can help improve sleep patterns affected by nocturia. Choices B, C, and D are incorrect. Drinking cranberry juice or warm decaffeinated beverage at bedtime may increase fluid intake, exacerbating the nocturia issue. Consulting the healthcare provider about a sleeping pill should not be the first intervention, as it is important to try non-pharmacological approaches first.

5. The healthcare provider selects the best site for insertion of an IV catheter in the client's right arm. Which documentation should the healthcare provider use to identify placement of the IV access?

• A. Left brachial vein
• B. Right cephalic vein
• C. Dorsal side of the right wrist
• D. Right upper extremity

Correct answer: B

Rationale: The correct answer is B: Right cephalic vein. The cephalic vein is a large, superficial vein located on the radial side of the forearm, making it the preferred site for IV access. It is often the best choice for insertion of an IV catheter due to its accessibility and low risk of complications, such as infiltration. Documenting the use of the right cephalic vein for IV access is crucial for accurate and safe patient care. Choices A, C, and D are incorrect because the left brachial vein, the dorsal side of the right wrist, and the right upper extremity are not typically preferred sites for IV catheter insertion and may not provide optimal access or outcomes.
