Question 1 of 9

Which of the following best describes the test to assess the function of cranial nerve (CN) X?

Correct Answer: D

Rationale: The correct answer is D because cranial nerve X, also known as the vagus nerve, controls the movement of the soft palate and uvula. Asking the patient to say "ahhh" assesses the function of CN X as the soft palate and uvula should elevate symmetrically. A: Observing the patient's ability to articulate specific words does not specifically test CN X function. B: Assessing movement of the hard palate and uvula with the gag reflex primarily tests CN IX (glossopharyngeal nerve). C: Having the patient stick out the tongue and observing for tremors or pulling to one side primarily tests CN XII (hypoglossal nerve).

Question 2 of 9

A father brings his 2-month-old infant to the clinic because the infant has had diarrhea for the last 24 hours. He says that his baby has not been able to keep any formula down and that the diarrhea has been occurring at least every 2 hours. The nurse suspects dehydration. Where should the nurse test skin mobility and turgor in this infant?

Correct Answer: A

Rationale: The correct answer is A: Over the sternum. When testing for skin mobility and turgor in infants, the sternum is the best location. This area is less affected by factors like fat distribution and muscle tone, providing a more accurate assessment of dehydration. The skin should be gently pinched and released to observe how quickly it returns to its normal position - delayed return indicates dehydration. The other choices are incorrect because testing over the forehead, forearms, or abdomen may not provide an accurate assessment due to variations in fat distribution, muscle tone, or skin elasticity in those areas.

Question 3 of 9

A patient with a middle ear infection asks the nurse,"What does the middle ear do?" The nurse says that the function of the middle ear is to:

Correct Answer: C

Rationale: Rationale: 1. The middle ear conducts sound vibrations from the outer ear to the inner ear via the ossicles. 2. This transmission is essential for the inner ear to convert the vibrations into electrical signals for the brain to interpret as sound. 3. Maintaining balance (A) is the function of the inner ear's vestibular system. 4. Interpreting sounds (B) is done by the brain, not the middle ear. 5. Increasing amplitude (D) would distort sound perception, not enable inner ear function.

Question 4 of 9

During the ear examination of an 80-year-old patient, which of the following would be a normal finding?

Correct Answer: C

Rationale: The correct answer is C: A thin, translucent membrane. In elderly patients, the tympanic membrane tends to become thinner and more translucent due to age-related changes. This is considered a normal finding as it is a common occurrence in older individuals. The other choices are incorrect because: A) Loss of high-tone frequency hearing is not a normal finding in an ear examination of an elderly patient, as age-related hearing loss typically affects high frequencies. B) Increased elasticity of the pinna is not a common age-related change and may indicate a different issue. D) A shiny pink tympanic membrane is not a typical finding in an elderly patient and could suggest inflammation or infection instead of a normal age-related change.

Question 5 of 9

A patient comes into the clinic complaining of facial pain, fever, and malaise. On examination, the nurse notes swollen turbinates and a purulent discharge from the nose. The patient also complains of a dull, throbbing pain in his cheeks and teeth on the right side and pain when the nurse palpates the areas. The nurse recognizes that this patient has:

Correct Answer: C

Rationale: Rationale: The patient's symptoms of facial pain, fever, malaise, swollen turbinates, purulent nasal discharge, pain in cheeks and teeth, and pain upon palpation all point towards maxillary sinusitis. The maxillary sinuses are located in the cheek area, and infection can lead to the described symptoms. Frontal sinusitis typically presents with forehead pain, and nasal polyps would not cause the specific symptoms mentioned. Posterior epistaxis involves bleeding from the back of the nose and is not consistent with the patient's symptoms. Therefore, the correct answer is C: maxillary sinusitis.

Question 6 of 9

The nurse is testing the hearing of a 78-year-old man. Which of the following age-related hearing changes should the nurse keep in mind? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A: Age-related hearing loss begins in the mid-40s. This is because presbycusis, or age-related hearing loss, typically starts around the mid-40s due to natural aging processes affecting the inner ear. Choice B is incorrect as the progression of hearing loss can vary, being gradual for some individuals but not necessarily slow for everyone. Choice C is incorrect as high-frequency tone loss, not low-frequency, is commonly associated with aging. Choice D is incorrect as difficulty hearing consonants is more related to specific types of hearing loss, not solely age-related changes.

Question 7 of 9

The tissue that connects the tongue to the floor of the mouth is the:

Correct Answer: D

Rationale: The correct answer is D: frenulum. The frenulum is a small fold of tissue that connects the tongue to the floor of the mouth. It helps to limit the movement of the tongue, preventing excessive movement that could lead to injury. The uvula (A) is a soft tissue dangling at the back of the throat, the palate (B) is the roof of the mouth, and papillae (C) are small raised structures on the tongue's surface. These structures are not involved in connecting the tongue to the floor of the mouth.

Question 8 of 9

Which of the following is a risk factor for ear infections in young children?

Correct Answer: D

Rationale: The correct answer is D: Second-hand cigarette smoke. Exposure to second-hand smoke can irritate and inflame the lining of the Eustachian tube, making young children more susceptible to ear infections. This is supported by research showing a clear link between exposure to cigarette smoke and increased rates of ear infections in children. Family history (A) may contribute to genetic predisposition but is not a direct risk factor. Air conditioning (B) does not directly cause ear infections. Excessive cerumen (C) can lead to blockages but is not a primary risk factor for infections.

Question 9 of 9

The nurse is preparing to assess the visual acuity of a 16-year-old patient. How would the nurse proceed?

Correct Answer: C

Rationale: The correct answer is C because the nurse should use the Snellen chart positioned 6.1 m (20 ft) away to assess visual acuity. This is the standard method for testing distance vision. The nurse should ask the patient to read the letters on the chart from the top row down, covering one eye at a time if necessary. This method provides an accurate measurement of visual acuity at a distance. A: Performing the confrontation test assesses visual fields, not visual acuity. B: Using a Jaeger card is for near vision testing, not distance visual acuity. D: Assessing the ability to read newsprint at a close distance does not provide an accurate measurement of visual acuity at a distance.
