Correct Answer: D

Rationale: The correct answer is D: "Prolonged use of a bottle can increase the risk for tooth decay and ear infections." This response is the best because it addresses the potential consequences of prolonged bottle use, which include tooth decay and ear infections. It educates the mother on the risks associated with using a bottle as a pacifier for an extended period. Rationale: 1. Tooth decay: Prolonged exposure to sugary liquids in the bottle can lead to tooth decay, as the sugar feeds bacteria in the mouth. 2. Ear infections: Bottle-feeding while lying down can increase the risk of ear infections due to fluid entering the Eustachian tube. 3. Education: The response educates the mother on the specific risks associated with prolonged bottle use, promoting informed decision-making. 4. Health promotion: By highlighting the potential negative outcomes, the nurse is advocating for the baby's health and well-being. Incorrect Choices: A: "You're right, bottles make

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).

Correct Answer: B

Rationale: The correct answer is B (XI; asking the patient to shrug her shoulders against resistance). This is the correct choice because the nurse suspects damage to the spinal accessory nerve (CN XI), which innervates the trapezius and sternocleidomastoid muscles. Asking the patient to shrug her shoulders against resistance tests the function of the trapezius muscle, which is innervated by CN XI. This examination helps to assess the integrity of the nerve and its ability to innervate the muscle. Palpating the anterior and posterior triangles (choice A) is not specific to CN XI function. Percussing the sternomastoid and submandibular neck muscles (choice C) is related to CN XII, not CN XI. Assessing for a positive Romberg's sign (choice D) is not relevant to testing the function of CN XI.

Correct Answer: B

Rationale: The correct answer is B: candidiasis. Candidiasis is a fungal infection caused by Candida albicans, commonly seen in immunocompromised individuals like cancer patients post-chemotherapy. The raw, red, and bleeding areas indicate mucosal irritation, while the white, cheesy coating represents fungal overgrowth. Carcinoma (choice A) refers to cancerous growths, which typically present differently. Leukoplakia (choice C) is a precancerous lesion characterized by white patches, not raw areas with bleeding. Koplik's spots (choice D) are small, white spots seen in the mouth in measles, not indicative of the described findings.

Correct Answer: C

Rationale: The correct answer is C: In an individual who is severely dehydrated. Decreased skin turgor is a clinical sign of dehydration, indicating loss of skin elasticity due to fluid loss. Severe dehydration leads to decreased skin turgor as the skin loses its ability to recoil when pinched. In cases of severe obesity (choice A), skin turgor is usually normal or increased due to excess adipose tissue. During childhood growth spurts (choice B), skin turgor is typically unaffected. Connective tissue disorders like scleroderma (choice D) can lead to changes in skin texture and appearance, but not necessarily decreased skin turgor.
