Nursing Elites

1. During a clinic visit, the mother of a 7-year-old reports to the nurse that her child is often awake until midnight playing and is then very difficult to awaken in the morning for school. Which assessment data should the nurse obtain in response to the mother's report?

• A. The occurrence of any episodes of sleep apnea
• B. The child's blood pressure, pulse, and respirations
• C. Length of rapid eye movement (REM) sleep that the child is experiencing
• D. Description of the family's home environment

Correct answer: D

Rationale: In response to the mother's report, the nurse should assess the family's home environment first to identify any factors that may hinder the establishment of bedtime routines conducive to sleep. Factors such as noise, light, distractions, or other environmental aspects could be contributing to the child's difficulty falling asleep at a reasonable hour and waking up in the morning.

2. The nurse is providing discharge teaching to a client with a new diagnosis of osteoporosis. Which instruction should the nurse include?

• A. Increase dietary intake of calcium-rich foods.
• B. Avoid activities that increase the risk of falls.
• C. Avoid prolonged exposure to sunlight.
• D. Increase intake of vitamin D supplements.

Correct answer: B

Rationale: Avoiding activities that increase the risk of falls (B) is the most crucial instruction for a client with osteoporosis to prevent fractures. Osteoporosis weakens bones, making them more susceptible to fractures from falls. While increasing calcium intake (A) is important for bone health, avoiding falls takes precedence to prevent immediate harm. Avoiding prolonged exposure to sunlight (C) is not directly related to osteoporosis management. Increasing vitamin D supplements (D) is beneficial for bone health, but fall prevention is more critical in this scenario.

3. A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The nurse plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?

• A. 75 ml/hr
• B. 150 ml/hr
• C. 225 ml/hr
• D. 300 ml/hr

Correct answer: B

Rationale: To calculate the infusion rate, set up a ratio proportion problem: 50 ml/20 min = x ml/60 min. Cross multiply to solve: 50 × 60 / 20 = 150 ml/hr. Therefore, the infusion pump should be set to deliver the secondary infusion at a rate of 150 ml/hr. Option A, 75 ml/hr, is incorrect because it does not account for the correct calculation. Option C, 225 ml/hr, is incorrect as it is too high a rate based on the calculation. Option D, 300 ml/hr, is also incorrect as it does not align with the correct calculation for the infusion rate.

4. When preparing to insert an indwelling urinary catheter, the nurse applies sterile gloves and then tests the catheter balloon for patency. What action should the nurse implement next?

• A. Place a sterile drape under the client's buttocks.
• B. Instruct the client to inhale and then exhale slowly.
• C. Discard the gloves and apply new sterile gloves.
• D. Apply a sterile lubricant to the end of the catheter.

Correct answer: D

Rationale: After testing the catheter balloon for patency, the nurse should proceed to apply a sterile lubricant to the end of the catheter. This lubrication helps facilitate the insertion of the catheter smoothly. Placing a sterile drape under the client's buttocks should have been done prior to this step. Discarding the gloves and applying new sterile gloves is not necessary at this point in the procedure. Instructing the client to inhale and exhale slowly is not part of the immediate steps for inserting an indwelling urinary catheter.

5. 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.
