Immune System Practice Questions Questions
Question 1 of 5
A nurse enters the room of a teenager after the physician has obtained informed consent for a voiding cystourethrogram. The teenager asks the nurse to explain the procedure again. The nurse tells the client that the client is asked to void after:
Correct Answer: C
Rationale: The correct answer is C: Injection of contrast dye into the bladder via a catheter. In a voiding cystourethrogram, contrast dye is indeed injected into the bladder via a catheter to visualize the urinary tract during voiding. This allows for the assessment of bladder and urethra function. Choices A and D are incorrect because radioisotopes are not typically used in this procedure. Choice B is incorrect as contrast dye is not injected into the bloodstream but rather directly into the bladder. Therefore, the correct answer is C as it accurately describes the procedure for a voiding cystourethrogram.
Question 2 of 5
The nurse admitting and assessing a teenage boy with suspected testicular torsion (twisted testicle) will most likely find which of the following manifestations in addition to possible nausea and vomiting and acute testicular pain?
Correct Answer: B
Rationale: The correct answer is B: Cremasteric reflex depressed or absent. Testicular torsion causes twisting of the spermatic cord, cutting off blood supply to the testicle, leading to severe pain, nausea, and vomiting. The cremasteric reflex, which causes the testicle to elevate when the inner thigh is stroked, is typically absent in cases of testicular torsion due to the severe pain and ischemia. Choices A, C, and D are incorrect as relief of pain with elevation of the testicle, pain or discomfort upon urination, and presence of white blood cells and bacteria in the urine are not typical manifestations of testicular torsion.
Question 3 of 5
A school-age client is recovering after abdominal surgery. The nurse is planning care for the return of bowel function. Which intervention should be included in the client’s plan of care?
Correct Answer: D
Rationale: The correct answer is D - Ambulate 3-4 times a day. Ambulation helps stimulate peristalsis and aids in the return of bowel function after abdominal surgery. Walking promotes movement in the abdomen, preventing complications like ileus. Fowler's position (choice A) may help with breathing but does not directly impact bowel function. Choosing a low-fat diet (choice B) is important for overall health but does not directly promote bowel function. Having a commode at the bedside (choice C) is convenient but does not actively facilitate the return of bowel function like ambulation does.
Question 4 of 5
The mother of an infant born prematurely at 32 weeks expresses the desire to breastfeed her child. The nurse correctly responds with which statement when the mother asks how long she should breastfeed her baby?
Correct Answer: D
Rationale: The correct answer is D: "Breast milk should be the only food for the first 6 months." This is based on the WHO recommendation that exclusive breastfeeding for the first 6 months of life provides optimal nutrition and protection for infants. Breast milk contains essential nutrients and antibodies crucial for the premature infant's growth and immune system development. Other choices are incorrect because: A: Introducing solid foods too early can be harmful to a premature infant's digestive system. B: While some mothers breastfeed for 2 years, it is not a specific guideline for premature infants. C: Breastfeeding for at least a month is not sufficient; exclusive breastfeeding for 6 months is recommended for all infants, including premature ones.
Question 5 of 5
What is helpful to tell a mother who is concerned about preventing sleep problems in her 2-year-old child?
Correct Answer: D
Rationale: The correct answer is D: Use a nightlight in the child’s room. This answer is correct because a nightlight can provide a sense of security for the child and help alleviate any fear of the dark, which is a common issue for young children. It can also help the child feel more comfortable and relaxed, promoting better sleep. Choice A is incorrect as always sleeping in a quiet, darkened room may not address the child's fear of the dark. Choice B is incorrect as high-carbohydrate snacks before bedtime can actually disrupt sleep. Choice C is incorrect as eliminating the afternoon nap may lead to overtiredness, making it harder for the child to fall asleep at night.
