A 72-year-old patient has a history of hypertension and chronic lung disease. An important question for the nurse to include in history-taking would be:

Correct Answer: D

Rationale: The correct answer is D: "Have you noticed any dryness in your mouth?" This question is important as dryness in the mouth can be a side effect of certain medications used to manage hypertension and chronic lung disease. Dry mouth can lead to oral health issues and impact the patient's overall well-being. A: "Do you use a fluoride supplement?" is not directly relevant to the patient's medical history of hypertension and lung disease. B: "Have you had tonsillitis in the last year?" is not as crucial as dry mouth in relation to managing hypertension and lung disease. C: "At what age did you get your first tooth?" is not pertinent to the current medical conditions and management of hypertension and lung disease. In summary, the question about dryness in the mouth is the most relevant as it pertains to potential medication side effects and oral health implications for the patient with hypertension and chronic lung disease.

Correct Answer: D

Rationale: The correct answer is D. In an acute infection, such as streptococcal pharyngitis, the tonsils may exhibit yellowish exudates due to bacterial pus formation. This is consistent with the presence of inflammation and infection. Choices A, B, and C describe varying degrees of tonsillar enlargement and white debris, which could be present in different conditions but are not as specific to acute infection. Therefore, the presence of yellowish exudates on the tonsils is the key indicator of an acute bacterial infection like strep throat.

Correct Answer: C

Rationale: The correct answer is C because the presentation of clear vesicles with an erythematous base around them at the lip-skin border is characteristic of herpes simplex virus 1 infection, commonly known as cold sores. Given the patient's recent travel to Hawaii, exposure to the virus is likely. This infection is self-limiting and typically heals in 4 to 10 days without the need for specific treatment. Choice A is incorrect because seeing a skin specialist may not be necessary for a self-limiting viral infection. Choice B is incorrect as a biopsy is not typically indicated for a clear clinical diagnosis of herpes simplex virus infection. Choice D is incorrect as riboflavin deficiency does not present with clear vesicles and erythema at the lip-skin border.

Correct Answer: C

Rationale: The correct answer is C: "This is a fungal infection caused by all the antibiotics you've received." The black, hairy tongue is a known side effect of prolonged antibiotic use, which disrupts the balance of normal oral flora and predisposes to fungal overgrowth, specifically of the yeast Candida. Antibiotics can eliminate the competing bacteria that normally keep Candida in check. Therefore, the patient's symptoms are most likely due to a fungal infection related to antibiotic therapy, rather than a bacterial issue or temporary overgrowth of hair. Biopsy is not necessary as the condition is commonly seen in this context and can be managed with appropriate treatment for fungal overgrowth.

Correct Answer: A

Rationale: The correct answer is A: Teeth that appear shorter. As people age, teeth naturally wear down and may appear shorter due to years of use. This is a normal part of the aging process. B: A smoother tongue is not a typical age-related change. C: Beefy red buccal mucosa may be indicative of an underlying health issue, not solely related to aging. D: A painless lump on the tongue could be a sign of a more serious condition and should be investigated further.
