1. A 3-year-old boy was successfully toilet trained prior to his admission to the hospital for injuries sustained from a fall. His parents are very concerned that the child has regressed in his toileting behaviors. Which information should the nurse provide to the parents?
- A. Children usually resume their toileting behaviors when they leave the hospital
- B. A retraining program will need to be initiated when the child returns home
- C. Diapering will be provided since hospitalization is stressful to preschoolers
- D. A potty chair should be brought from home so he can maintain his toileting skills
Correct answer: A
Rationale: Children often regress in toileting behaviors during hospitalization due to stress and changes in routine. However, they usually resume normal behaviors once they are discharged and back in their familiar environment. Providing reassurance to the parents that the child is likely to return to his previous toileting habits after leaving the hospital can help alleviate their concerns. Choices B, C, and D are incorrect because they do not address the normal pattern of behavior regression and recovery in toileting skills associated with hospitalization.
2. When administering diazepam, a benzodiazepine, 10 mg IV push PRN for a client with alcohol withdrawal symptoms, which actions should the nurse implement? (Select all that apply)
- A. Protect the medication from light exposure
- B. Monitor for changes in level of consciousness
- C. Observe for onset of generalized bruising or bleeding
- D. Perform ongoing assessment of respiratory status
Correct answer: D
Rationale: When administering diazepam for a client with alcohol withdrawal symptoms, it is crucial to perform ongoing assessment of respiratory status. Diazepam can lead to respiratory depression, emphasizing the need for continuous monitoring to detect any signs of respiratory distress early. Protecting the medication from light exposure is a general guideline for some drugs but is not a specific concern for diazepam. Observing for bruising or bleeding is not directly associated with the administration of diazepam for alcohol withdrawal symptoms, making choices A and C incorrect.
3. The nurse is assessing a client with Addison's disease who is weak, dizzy, disoriented, and has dry oral mucous membranes, poor skin turgor, and sunken eyes. Vital signs are blood pressure 94/44, heart rate 123 beats/minute, respiration 22 breaths/minute. Which intervention should the nurse implement first?
- A. Assess extremity strength and resistance
- B. Report a sodium level of 132 mEq/L or mmol/L (SI units)
- C. Measure and record the cardiac QRS complex
- D. Check current finger stick glucose
Correct answer: D
Rationale: The client’s symptoms suggest possible adrenal crisis or hypoglycemia. Checking glucose is a priority to rule out hypoglycemia, which requires immediate intervention. The client is presenting with symptoms indicative of hypoglycemia, which can be life-threatening if not promptly addressed. Assessing extremity strength, reporting sodium levels, or measuring the cardiac QRS complex are not the most urgent actions in this scenario.
4. After receiving report, which client should the nurse assess last?
- A. An older client with dark red drainage on a postoperative dressing, but no drainage in the Hemovac
- B. An adult client with no postoperative drainage in the Jackson-Pratt drain with the bulb compressed
- C. An older client with a distended abdomen and no drainage from the nasogastric tube
- D. An adult client with rectal tube draining clear pale red liquid drainage
Correct answer: D
Rationale: The correct answer is D because the client with rectal tube drainage of clear pale red liquid is likely to be the least urgent since this is a normal post-operative finding. Clear pale red liquid drainage from a rectal tube is typically not a cause for immediate concern. Choices A, B, and C present clients with concerning signs that may require more immediate assessment and intervention. A client with dark red drainage on a postoperative dressing may indicate active bleeding, a client with a compressed Jackson-Pratt drain bulb may have inadequate drainage resulting in complications, and a client with a distended abdomen and no drainage from the nasogastric tube may be experiencing gastrointestinal issues that need prompt evaluation.
5. When caring for a client with Cushing syndrome, which serum laboratory value is most important for the nurse to monitor?
- A. Lactate
- B. Glucose
- C. Hemoglobin
- D. Creatinine
Correct answer: B
Rationale: When caring for a client with Cushing syndrome, monitoring glucose levels is crucial as Cushing syndrome often leads to hyperglycemia. Elevated glucose levels are a common manifestation of Cushing syndrome due to increased cortisol levels. Monitoring glucose helps in assessing and managing the client's condition effectively. Lactate levels are not typically affected by Cushing syndrome. Hemoglobin and creatinine levels are important for other conditions like anemia and kidney function, but they are not the priority in Cushing syndrome.
