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 changing the route of administration from PO to IV, the absorption process is bypassed, leading to a more rapid onset of action of the medication and consequently a quicker effect. Choices A, C, and D are incorrect. Increased drug tolerance and higher doses are not typical outcomes of changing the route of administration. Protein binding does not increase with a change to IV administration; rather, it is the bioavailability and onset of action that are affected. Moreover, an increased therapeutic index reduces the risk of drug toxicity, contrary to what is stated in choice D.

The nurse assesses a 2-year-old who is admitted for dehydration and finds that the peripheral IV rate by gravity has slowed, even though the venous access site is healthy. What should the nurse do next?
- A. Apply a warm compress proximal to the site.
- B. Check for kinks in the tubing and raise the IV pole.
- C. Adjust the tape that stabilizes the needle.
- D. Change the IV solution bag.
Correct Answer: B
Rationale: When a nurse assesses a slowed IV rate by gravity with a healthy venous access site in a 2-year-old admitted for dehydration, the next step would be to check for kinks in the tubing and raise the IV pole. This action ensures that the IV fluid can flow freely and reach the patient at the correct rate. Applying a warm compress proximal to the site (Choice A) is not indicated in this situation as it does not address the underlying issue of a slowed IV rate due to mechanical factors. Adjusting the tape that stabilizes the needle (Choice C) or changing the IV solution bag (Choice D) are not the priority actions in this case. These choices do not address the issue of a slowed IV rate caused by kinks in the tubing or the height of the IV pole, which are more likely reasons for the problem observed.
When performing a return demonstration of using a gait belt for a female patient with right-sided weakness, which observation indicates that the caregiver has learned the correct procedure?
- A. Standing on the female patient's strong side, the caregiver is ready to hold the gait belt if any evidence of weakness is observed.
- B. Standing on the female patient's weak side, the caregiver provides security by holding the gait belt from the back.
- C. Standing behind the female patient, the caregiver provides balance by holding both sides of the gait belt.
- D. Standing slightly in front and to the right of the female patient, the caregiver guides her forward by gently pulling on the gait belt.
Correct Answer: B
Rationale: When assisting a patient with right-sided weakness using a gait belt, the caregiver must stand on the weak side of the patient to provide optimal support and security. By standing on the weak side and holding the gait belt from the back, the caregiver can effectively prevent falls and guide the patient's movements. This position allows for better control over the patient's balance. Standing on the strong side (option A) does not offer the necessary support if the patient leans towards the weak side. Standing behind the patient and holding both sides of the gait belt (option C) does not provide focused support to the weak side. Standing slightly in front and to the right (option D) may not offer adequate assistance to prevent falls on the weak side, making it an incorrect choice.
The nurse-manager of a skilled nursing (chronic care) unit is instructing UAPs on ways to prevent complications of immobility. Which intervention should be included in this instruction?
- A. Perform range-of-motion exercises to prevent contractures.
- B. Decrease the client's fluid intake to prevent diarrhea.
- C. Massage the client's legs to reduce embolism occurrence.
- D. Turn the client from side to back every shift.
Correct Answer: A
Rationale: Performing range-of-motion exercises is beneficial in reducing contractures around joints, maintaining joint mobility, and preventing stiffness in immobile clients. This intervention helps preserve muscle strength and joint function. Options B, C, and D are incorrect because: Option B suggesting decreasing fluid intake to prevent diarrhea is not relevant to preventing complications of immobility and could lead to dehydration; Option C, massaging the client's legs to reduce embolism occurrence, is not a recommended practice as massage can dislodge blood clots and increase the risk of embolism; Option D, turning the client from side to back every shift, is not sufficient as it does not address the need for maintaining joint mobility and preventing contractures in immobile clients.
The client with partial-thickness (second-degree) and full-thickness (third-degree) burns is at risk of infection. What intervention has the highest priority in decreasing the client's risk of infection?
- A. Administration of plasma expanders
- B. Use of careful handwashing technique
- C. Application of a topical antibacterial cream
- D. Limiting visitors to the client with burns
Correct Answer: B
Rationale: The correct answer is the use of careful handwashing technique. Proper handwashing is the most effective way to prevent the transmission of infectious organisms. Option A, administration of plasma expanders, addresses hypovolemia in burn patients but does not directly decrease the risk of infection. Option C, application of a topical antibacterial cream, is beneficial but not as effective as proper handwashing in preventing infection. Option D, limiting visitors, may help reduce the risk of exposure to pathogens but is not as critical as ensuring healthcare providers maintain strict hand hygiene, which is the cornerstone of infection control in any healthcare setting.
A client in a long-term care facility reports to the nurse that he has not had a bowel movement in 2 days. Which intervention should the nurse implement first?
- A. Instruct the caregiver to offer a glass of warm prune juice at mealtimes.
- B. Notify the healthcare provider and request a prescription for a large-volume enema.
- C. Assess the client's medical record to determine the client's normal bowel pattern.
- D. Instruct the caregiver to increase the client's fluids to five 8-ounce glasses per day.
Correct Answer: C
Rationale: The first step in addressing a client's reported change in bowel habits is to assess the client's normal bowel pattern. This assessment helps the nurse understand the client's typical bowel habits and identify any deviations from the norm. By assessing the medical record first, the nurse gains valuable information that guides further interventions. In this scenario, offering prune juice (Option A) or increasing fluids (Option D) may not be appropriate until the client's normal bowel pattern is known. Notifying the healthcare provider for a large-volume enema (Option B) is premature without understanding the client's baseline. Therefore, assessing the client's medical record is the priority before proceeding with any interventions.
