One of the major functions of the kidneys in maintaining normal fluid balance is:
- A. the manufacture of antidiuretic hormone.
- B. the regulation of calcium and phosphate balance.
- C. the regulation of the pH of the extracellular fluid.
- D. the control of aldosterone levels.
Correct Answer: C
Rationale: The correct answer is 'the regulation of the pH of the extracellular fluid.' The kidneys play a crucial role in maintaining normal fluid balance by regulating extracellular fluid and osmolarity through selective retention and excretion of fluids. Additionally, they regulate the pH of the extracellular fluid by retaining hydrogen ions and excreting metabolic wastes and toxic substances. Choice A is incorrect because antidiuretic hormone (ADH) is manufactured by the pituitary gland, not the kidneys. Choice B is incorrect as the regulation of calcium and phosphate balance is primarily controlled by the parathyroid gland. Choice D is incorrect as aldosterone levels are controlled by the adrenal glands, not the kidneys.

How can a diet high in fiber content benefit an individual?
- A. aid in rapid weight loss.
- B. reduce diabetic ketoacidosis.
- C. lower cholesterol.
- D. reduce the requirement for folate.
Correct Answer: C
Rationale: A diet high in fiber content can help lower cholesterol levels. Fiber-rich foods such as grains, apples, potatoes, and beans are known to aid in reducing cholesterol by binding to cholesterol in the digestive system and preventing its absorption into the bloodstream. Choice A is incorrect as the question does not specify losing weight rapidly but rather focuses on the benefits of a high-fiber diet, which includes aiding in weight management through promoting satiety and regulating digestion. Choice B is incorrect because while fiber helps manage blood sugar levels, it is not directly related to reducing diabetic ketoacidosis, a serious complication of diabetes. Choice D is incorrect as a high-fiber diet does not reduce the need for folate; however, it can aid in the absorption of folate and other essential nutrients.
A high school nurse observes a 14-year-old female rubbing her scalp excessively in the gym. What is the most appropriate course of action for the nurse?
- A. Request the female’s parents for a private evaluation of her scalp
- B. Contact the female’s parents regarding the observations
- C. Observe the hairline and scalp for possible signs of lice
- D. Inform the student’s physician about the situation
Correct Answer: C
Rationale: The most appropriate course of action for the nurse is to observe the hairline and scalp for possible signs of lice. The student's behavior of excessively rubbing her scalp raises concerns about a potential infestation, making it necessary to look for signs firsthand. Contacting the parents or the physician should be considered after observing for signs of lice to provide more information and take appropriate action. Requesting a private evaluation from the parents may not be required initially, as lice infestation is a common concern among children and observing for signs is the immediate step to address the situation.
The nurse teaching about preventable diseases should emphasize the importance of getting the following vaccines:
- A. human papillomavirus, genital herpes, measles.
- B. pneumonia, HIV, mumps.
- C. syphilis, gonorrhea, pneumonia.
- D. polio, pertussis, measles.
Correct Answer: D
Rationale: Vaccines are one of the most effective methods of preventing and controlling certain communicable diseases. The smallpox vaccine is not currently in use because the smallpox virus has been declared eradicated from the world's population. Diseases such as polio, diphtheria, pertussis, and measles are mostly controlled by routine childhood immunization. They have not, however, been eradicated, so children need to be immunized against these diseases. Choices A, B, and C contain vaccines that do not protect against preventable diseases like polio, pertussis, and measles. Therefore, the correct choice is D.
A client had a Caesarean delivery and is postpartum day 1. She asks for pain medication when the nurse enters the room to do her shift assessment. The client states that her pain level is an 8 on a scale of 1 to 10. What should be the nurse's priority of care?
- A. Give the pain medication and return in an hour for further assessment to allow time for the medication to work.
- B. Complete the postpartum assessment and then give the client pain medication.
- C. Give the pain medication first, do a quick assessment while administering the medication to ensure the pain is not caused by a complication, and return for the full assessment after the client's pain has subsided.
- D. Instruct the patient to do relaxation exercises to relieve her discomfort.
Correct Answer: C
Rationale: Pain management is a priority, so the nurse should immediately provide pain medication. However, the nurse should conduct a quick assessment while administering the medication to ensure that a complication, such as hemorrhage, hasn't caused the increased pain. A complete assessment can wait until the pain subsides. Controlling pain will enable the client to move, eliminating other potential complications of delivery and facilitating bonding with the infant. Relaxation techniques can act as an adjunct therapy but by themselves are not usually effective for pain management during the early post-Caesarean period.
The LPN is preparing to ambulate a client post total knee replacement. Which of the following actions should the nurse perform prior to ambulating the client?
- A. Assist the client to a sitting position at the edge of the bed
- B. Have the client march in place for 30 seconds
- C. Have the client raise his arms above his head
- D. Ask the client the last time he fell
Correct Answer: A
Rationale: The correct action to perform before ambulating a client post total knee replacement is to assist the client to a sitting position at the edge of the bed. This step is crucial to prevent orthostatic hypotension and ensure the client is ready to stand and walk safely. Having the client march in place or raise his arms above his head are not necessary preparations for ambulation. While knowing about the client's fall history is important for safety reasons, it is not the priority action immediately before ambulating the client.
