The healthcare provider is assessing the laboratory results for a client who is admitted with renal failure and osteodystrophy. Which findings are consistent with this client's clinical picture?
- A. Serum potassium of 4.0 mEq/L and total calcium of 9 mg/dL.
- B. White blood cell count of 15,000/mm3.
- C. Serum potassium of 5.5 mEq/L and total calcium of 6 mg/dL.
- D. Hemoglobin of 12 g/dL and phosphorus of 2 mg/dL.
Correct Answer: C
Rationale: In renal failure and osteodystrophy, there is an alteration in serum electrolyte balance. The correct answer is serum potassium of 5.5 mEq/L and total calcium of 6 mg/dL. Renal failure is associated with hyperkalemia (elevated serum potassium) and hypocalcemia (low total calcium levels). Hyperphosphatemia is also commonly seen in renal failure. Choice A is incorrect as it describes normal levels of serum potassium and total calcium. Choice B is unrelated to the client's condition. Choice D is incorrect as it does not reflect the typical electrolyte imbalances seen in renal failure and osteodystrophy.

A public health nurse is implementing a program to improve vaccination rates among children in the community. Which intervention is most likely to be effective?
- A. Offering vaccinations at convenient locations and times
- B. Distributing educational materials about vaccines
- C. Providing incentives for getting vaccinated
- D. Hosting informational sessions for parents
Correct Answer: A
Rationale: Offering vaccinations at convenient locations and times is the most effective intervention as it reduces barriers to access and makes it easier for parents to get their children vaccinated. This strategy directly addresses the issue of convenience and accessibility, which are common reasons for low vaccination rates. Distributing educational materials about vaccines (Choice B) can be helpful but may not directly address access issues. Providing incentives for getting vaccinated (Choice C) may be controversial and not sustainable in the long term. Hosting informational sessions for parents (Choice D) can be beneficial for education but may not directly improve vaccination rates as much as increasing access.
The healthcare provider is preparing to administer an intravenous antibiotic to a client with a central venous catheter. Which action is most important?
- A. Flush the catheter with heparin.
- B. Change the dressing at the insertion site.
- C. Check for blood return before administering the antibiotic.
- D. Use sterile technique when accessing the catheter.
Correct Answer: D
Rationale: Using sterile technique when accessing the catheter is crucial to prevent infection in clients with a central venous catheter. This action helps maintain asepsis and reduces the risk of introducing pathogens into the catheter system. Flushing the catheter with heparin helps prevent occlusion but is not as crucial as ensuring sterile technique. Changing the dressing at the insertion site is important for assessing the site's condition but does not directly impact the administration of the antibiotic. Checking for blood return is essential to ensure proper catheter function, but sterile technique takes precedence to prevent infections.
A community health nurse is evaluating the effectiveness of a diabetes management program. Which outcome indicates that the program is successful?
- A. increased attendance at diabetes education sessions
- B. reduced incidence of diabetes-related hospitalizations
- C. higher rates of blood glucose monitoring among participants
- D. greater knowledge of diabetes management techniques
Correct Answer: B
Rationale: The correct answer is B: reduced incidence of diabetes-related hospitalizations. This outcome is a strong indicator of successful diabetes management, as it suggests that participants are effectively controlling their condition and experiencing fewer severe complications that require hospitalization. Increased attendance at education sessions (choice A) may not directly correlate with improved health outcomes. While higher rates of blood glucose monitoring (choice C) are important, they alone may not reflect overall program success. Greater knowledge of diabetes management techniques (choice D) is valuable but does not directly measure the impact of the program on health outcomes like reduced hospitalizations.
The healthcare professional is developing a program to educate parents on the importance of immunizations. Which topic should be prioritized?
- A. the benefits of immunizations
- B. the potential side effects of vaccines
- C. the immunization schedule
- D. ways to comfort children during vaccinations
Correct Answer: A
Rationale: Prioritizing the benefits of immunizations is crucial in helping parents comprehend the significance of vaccines in safeguarding their children against preventable diseases. Understanding the positive impact of immunizations can alleviate concerns and misconceptions that parents may have, ultimately encouraging them to make informed decisions regarding their children's health. Discussing potential side effects (choice B) is important but should come after highlighting the benefits to avoid instilling unnecessary fear. While the immunization schedule (choice C) is essential information, it may be overwhelming if presented as the initial focus. Comforting children during vaccinations (choice D) is valuable but secondary to ensuring parents understand the benefits of immunizations.
A client with a history of seizures is admitted with status epilepticus. Which medication should the nurse prepare to administer?
- A. Phenytoin (Dilantin)
- B. Diazepam (Valium)
- C. Lorazepam (Ativan)
- D. Carbamazepine (Tegretol)
Correct Answer: C
Rationale: In the management of status epilepticus, the initial medication of choice is a benzodiazepine to rapidly terminate the seizure activity. Lorazepam (Ativan) is preferred over Diazepam (Valium) due to its longer duration of action and lower risk of respiratory depression. Phenytoin (Dilantin) and Carbamazepine (Tegretol) are not the first-line agents for the acute treatment of status epilepticus, making them incorrect choices in this scenario.
