1. A teenage client is admitted to the hospital because of acetaminophen (Tylenol) overdose. Overdoses of acetaminophen can precipitate life-threatening abnormalities in which of the following organs?
- A. lungs
- B. liver
- C. kidneys
- D. adrenal glands
Correct answer: B
Rationale: Acetaminophen is extensively metabolized in the liver. An overdose of acetaminophen can lead to severe liver damage and even liver failure, which can be life-threatening. Choices A, C, and D are incorrect because although prolonged use of acetaminophen may lead to an increased risk of renal dysfunction, a single overdose does not typically cause life-threatening abnormalities in the lungs, kidneys, or adrenal glands.
2. During the examination of a client's throat, a nurse touches the posterior wall with a tongue blade and elicits the gag reflex. The nurse documents normal function of which cranial nerves?
- A. Cranial nerves V and VI
- B. Cranial nerves XII and VIII
- C. Cranial nerves XII and VIII
- D. Cranial nerves IX and X
Correct answer: D
Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.
3. A nurse assisting with data collection regarding the client's eyes notes that the pupils get larger when the client looks at an object in the distance and become smaller when the client looks at a nearby object. How does the nurse document this finding?
- A. Myopia
- B. Hyperopia
- C. Photophobia
- D. Accommodation
Correct answer: D
Rationale: The correct answer is Accommodation. Accommodation is the process by which the eye adjusts its focus to see objects at different distances. When the pupils get larger when the client looks at an object in the distance and become smaller when looking at a nearby object, it indicates the normal functioning of the eye's accommodation mechanism. Myopia refers to nearsightedness, where distant objects appear blurry. Hyperopia refers to farsightedness, where close objects appear blurry. Photophobia is an abnormal sensitivity to light. Therefore, the correct term to document the finding of the pupils adjusting based on the distance of the object is 'Accommodation.'
4. A nurse is determining the fetal heart rate (FHR) and places the fetoscope on the mother's abdomen to count the FHR. The nurse simultaneously palpates the mother's radial pulse and notes that it is synchronized with the sounds heard through the fetoscope. Which action should the nurse take?
- A. Count the FHR for 60 seconds, ensuring that it is synchronized consistently with the mother's radial pulse.
- B. Move the fetoscope to another area on the mother's abdomen to locate the fetal heart.
- C. Ask the mother to lie still while both the FHR and the radial pulse rate are counted.
- D. Count the FHR for 30 seconds and then count the radial pulse rate of the mother for 30 seconds.
Correct answer: B
Rationale: When auscultating the fetal heart rate, the nurse would place the fetoscope on the maternal abdomen, over the fetal back. The nurse would then palpate the mother's radial pulse. If her pulse is synchronized with the sounds from the fetoscope, the nurse would move the fetoscope to another area on the mother's abdomen to locate the FHR. The nurse needs to be sure that the FHR is what is actually being heard. Other sounds that may be heard are the funic sound (blood flowing through the umbilical cord) and the uterine sound (blood flowing through the uterine vessels). The funic sound is synchronized with the FHR; the uterine sound is synchronized with the mother's pulse. Therefore, moving the fetoscope to a different area will help in accurately locating and counting the fetal heart rate. Choice A is incorrect because counting for 60 seconds without changing the position may not address the issue of accurately locating the FHR. Choice C is incorrect as it does not address the need to reposition the fetoscope to locate the fetal heart. Choice D is incorrect because counting the FHR and the radial pulse rate separately may not help in differentiating the two sounds.
5. Intramuscular (IM) phytonadione (vitamin K) 0.5 mg is prescribed for a newborn. After the medication is prepared, in which anatomic site does the nurse administer it?
- A. Rectus femoris muscle
- B. Deltoid muscle
- C. Gluteal muscle
- D. Vastus lateralis muscle
Correct answer: D
Rationale: Vitamin K is administered to newborn infants to help prevent hemorrhagic disease. The best site for intramuscular injection in infants is the vastus lateralis muscle. This site is preferred due to its location away from the sciatic nerve, femoral artery, and vein, reducing the risk of complications. The rectus femoris muscle may be used if necessary; however, it is less favorable than the vastus lateralis due to its proximity to vital structures, making injections there more hazardous. The deltoid muscle is not typically used for IM injections in newborns. The gluteal muscles should be avoided until the child has been walking for at least a year, as they are poorly developed and close to the sciatic nerve.
