1. When assessing a client's skin turgor, a nurse should:
- A. Grasp a fold of the skin on the chest under the clavicle, release it, and note the depth of the impression
- B. Check skin elasticity on the back of the hand
- C. Press on the skin over the abdomen
- D. Measure skin turgor on the lower leg
Correct answer: A
Rationale: Correct answer: When assessing a client's skin turgor, a nurse should grasp a fold of the skin on the chest under the clavicle, release it, and note the depth of the impression. This method is reliable for evaluating hydration status as it is less influenced by age-related skin changes or adipose tissue. Choice B, checking skin elasticity on the back of the hand, is not the preferred method for assessing skin turgor. Choice C, pressing on the skin over the abdomen, is not a standard location for assessing skin turgor. Choice D, measuring skin turgor on the lower leg, is not a recommended site for assessing skin turgor in clinical practice.
2. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.
3. A nurse is providing home care for a client who is receiving tube feedings and medication through a gastrostomy tube. The family member providing the feedings reports that the client has begun to have diarrhea. For which of the following practices should the nurse intervene?
- A. The family member washes out the feeding bag with warm water once every 24 hours.
- B. The family member washes out the feeding bag with hot water once every 24 hours.
- C. The family member washes out the feeding bag with soap and water every 24 hours.
- D. The family member changes the feeding bag every 24 hours.
Correct answer: A
Rationale: The correct answer is A. Washing out the feeding bag with warm water once every 24 hours is not sufficient to prevent bacterial growth and can lead to diarrhea. Using hot water may damage the feeding bag. Washing out the feeding bag with soap and water every 24 hours is excessive and may leave residue that could be harmful. Changing the feeding bag every 24 hours is important for preventing infections but does not directly address the issue of diarrhea in this case.
4. A client with schizophrenia is being discharged with a prescription for risperidone (Risperdal). What is the most important instruction for the nurse to provide?
- A. Stop taking the medication if you start feeling better.
- B. Be aware of the potential for weight gain with this medication.
- C. Report any unusual muscle movements immediately.
- D. You can drive as soon as you feel ready.
Correct answer: C
Rationale: The correct answer is C: "Report any unusual muscle movements immediately." Unusual muscle movements may indicate extrapyramidal symptoms (EPS) or tardive dyskinesia, which are serious side effects of antipsychotic medications like risperidone. It is crucial to address these symptoms promptly to prevent long-term effects. Choice A is incorrect because stopping the medication suddenly can be dangerous and should only be done under medical supervision. Choice B, while important, is not the most critical instruction in this scenario. Choice D is also incorrect as the ability to drive may be affected by the medication and should be discussed with a healthcare provider.
5. Which organ lies retroperitoneally?
- A. Kidneys
- B. Testicles
- C. Urinary bladder
- D. Pancreas
Correct answer: A
Rationale: The correct answer is A: Kidneys. The kidneys are located retroperitoneally, behind the peritoneum, providing structural protection and maintaining a stable position within the abdominal cavity. This location helps protect them from external physical trauma. Choices B, C, and D are incorrect because testicles, urinary bladder, and pancreas are not located retroperitoneally. Testicles are located in the scrotum, the urinary bladder is located in the pelvis, and the pancreas is located in the upper abdomen, not retroperitoneally.
