A client with cirrhosis is receiving lactulose. What is the desired effect of this medication?
- A. Decrease blood glucose levels
- B. Reduce serum ammonia levels
- C. Increase platelet count
- D. Lower serum bilirubin levels
Correct Answer: B
Rationale: The correct answer is B: Reduce serum ammonia levels. Lactulose is used to reduce serum ammonia levels in clients with cirrhosis, helping to prevent hepatic encephalopathy. Lactulose works by acidifying the colon, trapping ammonia for excretion. Decreasing blood glucose levels (choice A) is not the primary effect of lactulose. Increasing platelet count (choice C) and lowering serum bilirubin levels (choice D) are not direct effects of lactulose in the management of cirrhosis.

Which is a priority nursing intervention for the cognitively impaired child?
- A. The family will provide good nutrition.
- B. The family will provide loving interactions.
- C. Stimulation will improve.
- D. There will be contact with peers.
Correct Answer: B
Rationale: The correct answer is B because nursing interventions for cognitively impaired children prioritize promoting loving interactions with family. This support helps in creating a nurturing environment that contributes to the child's well-being and development. Choice A is not the priority as good nutrition, though important, may not address the immediate emotional and social needs of the child. Choice C is vague and does not specify how stimulation will be provided. Choice D, contact with peers, is also valuable but not as crucial as the primary relationships and interactions within the family unit for a cognitively impaired child.
The nurse is preparing a client for surgery who was admitted to the emergency center following a motor vehicle collision. The client has an open fracture of the femur and is bleeding moderately from the bone protrusion site.
- A. Ensure the client is NPO and document the last meal.
- B. Administer pain medication as prescribed.
- C. Apply a sterile dressing to the wound site.
- D. Notify the healthcare provider of the client's medication history.
Correct Answer: D
Rationale: In this scenario, the priority action is to notify the healthcare provider of the client's medication history. This is important because understanding the client's medication history, especially if they are taking anticoagulants or other medications that could affect bleeding and surgery, is crucial in ensuring safe management of the client's condition. Option A, ensuring the client is NPO and documenting the last meal, is important but not the priority in this situation. Administering pain medication (Option B) should only be done after ensuring the client's safety and stability. Applying a sterile dressing (Option C) is also important but not as critical as informing the healthcare provider of the medication history.
The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?
- A. Bilateral crackles in the lung bases.
- B. Low-pressure indicator alarm.
- C. Oxygen saturation of 91%.
- D. Respiratory rate of 18 breaths/minute.
Correct Answer: B
Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.
How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?
- A. They involve antigen-antibody complexes.
- B. They are mediated by T cells and do not involve antibodies.
- C. They result in immediate allergic reactions.
- D. They are the least severe form of hypersensitivity.
Correct Answer: B
Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.
An older adult with chronic obstructive pulmonary disease (COPD) was recently admitted to the hospital with heart failure (HF). Which actions should the nurse take in providing care? (Select all that apply)
- A. Monitor electrolyte levels.
- B. Maintain pulse oximetry.
- C. Provide assistance with mobility.
- D. All of the Above
Correct Answer: D
Rationale: In a patient with COPD and HF, monitoring electrolyte levels is essential due to potential imbalances caused by medications or fluid shifts. Maintaining pulse oximetry is crucial to assess oxygenation status in COPD and HF. Providing assistance with mobility helps prevent deconditioning and complications. Therefore, all the actions mentioned are necessary for comprehensive care in this scenario, making option D the correct answer. Choices A, B, and C are all important aspects of managing COPD and HF, ensuring holistic and effective care.
