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. A client with acute renal failure (ARF) is admitted for uncontrolled type 1 diabetes mellitus and hyperkalemia. The nurse administers an IV dose of regular insulin per sliding scale. Which intervention is the most important for the nurse to include in this client’s plan of care?
- A. Monitor the client’s cardiac activity via telemetry.
- B. Maintain venous access with an infusion of normal saline.
- C. Assess glucose levels via finger stick every 4 to 6 hours.
- D. Evaluate hourly urine output for the return of normal renal function.
Correct answer: A
Rationale: Monitoring cardiac activity is crucial in this scenario because hyperkalemia can lead to serious cardiac dysrhythmias, which can be life-threatening. Regular monitoring of the client’s cardiac activity via telemetry allows for early detection of any potential cardiac complications. Maintaining venous access with a normal saline infusion is important for hydration but does not address the immediate risk of cardiac dysrhythmias posed by hyperkalemia. Assessing glucose levels is essential in diabetes management but is not the priority when dealing with hyperkalemia-induced cardiac risks. Evaluating hourly urine output for the return of normal renal function is important in ARF but is not as urgent as monitoring the client's cardiac activity in the context of hyperkalemia.
3. Which laboratory finding should the nurse expect to see in a child with acute rheumatic fever?
- A. Thrombocytopenia
- B. Polycythemia
- C. Decreased ESR
- D. Positive ASO titer
Correct answer: D
Rationale: The correct answer is D: Positive ASO titer. A positive ASO titer indicates recent streptococcal infection, which is associated with acute rheumatic fever. Thrombocytopenia (choice A) is not a typical laboratory finding in acute rheumatic fever. Polycythemia (choice B) refers to an increased red blood cell count, which is not typically seen in acute rheumatic fever. Decreased ESR (choice C) is not a common laboratory finding in acute rheumatic fever; in fact, ESR is often elevated in inflammatory conditions like rheumatic fever.
4. When assessing a mildly obese 35-year-old female client, the nurse is unable to locate the gallbladder when palpating below the liver margin at the lateral border of the rectus abdominal muscle. What is the most likely explanation for the failure to locate the gallbladder by palpation?
- A. The client is too obese.
- B. Palpating in the wrong location.
- C. The gallbladder is normal.
- D. Deeper palpation technique is needed.
Correct answer: A
Rationale: The correct answer is A. Obesity can make it difficult to palpate the gallbladder due to increased abdominal tissue, making it challenging to locate specific structures. Choice B is incorrect because the nurse is palpating in the correct location below the liver margin at the lateral border of the rectus abdominal muscle, where the gallbladder is typically located. Choice C is incorrect as the inability to palpate the gallbladder does not necessarily indicate abnormality; it may be due to anatomical variations or technical challenges. Choice D is incorrect as the issue lies more with the difficulty posed by excess adipose tissue rather than the need for deeper palpation techniques.
5. The nurse is preparing an older client for discharge following cataract extraction. Which instruction should be included in the discharge teaching?
- A. Do not read with direct lighting for 6 weeks
- B. Avoid straining during stool passage, bending, or lifting heavy objects
- C. Irrigate conjunctiva with ophthalmic saline after applying antibiotic ointment
- D. Limit exposure to sunlight during the first 2 weeks while the cornea is healing
Correct answer: B
Rationale: The correct instruction to include in the discharge teaching for a client following cataract extraction is to 'Avoid straining during stool passage, bending, or lifting heavy objects.' This is crucial to prevent increased intraocular pressure after surgery, which can be harmful. Reading with direct lighting can strain the eyes but is not the primary concern post-cataract surgery. Irrigating the conjunctiva before applying antibiotic ointment is not a standard practice and may not be necessary. While limiting sunlight exposure is important for eye protection, it is secondary to avoiding activities that can increase intraocular pressure.
