A patient with a diagnosis of giardiasis is being treated with metronidazole (Flagyl). What information would be important to obtain before prescribing this medication?

Correct Answer: D

Rationale: In the context of pharmacology and the treatment of giardiasis with metronidazole (Flagyl), it is crucial to obtain information about the patient's alcohol consumption habits before prescribing this medication. Metronidazole interacts with alcohol, leading to a disulfiram-like reaction that can cause severe nausea, vomiting, flushing, and headache. Therefore, it is essential to ensure that the patient does not consume alcohol while on this medication to avoid these adverse effects and ensure treatment efficacy. Regarding the other options: A) Inquiring about sulfa allergy is important when prescribing sulfonamide antibiotics, not metronidazole. B) The presence of peptic ulcer disease is not directly relevant to the use of metronidazole for giardiasis treatment. C) The age of the patient, as long as they are not a child (for whom different considerations apply), is generally not a crucial factor in determining the appropriateness of metronidazole for giardiasis treatment. In an educational context, understanding the importance of obtaining comprehensive patient information before prescribing medications is vital for safe and effective pharmacological interventions. Educating healthcare providers about potential drug interactions, contraindications, and patient-specific factors helps in promoting optimal patient outcomes and preventing medication errors.

Correct Answer: B

Rationale: The correct answer is B) Lindane lotion and/or shampoo is not considered first-line therapy for treating scabies. This is because lindane is associated with serious side effects, including neurotoxicity, and can be absorbed through the skin. Therefore, it is reserved for cases where other treatments have failed or cannot be tolerated. Option A is incorrect because lindane is not safe for use in pregnant women, babies, children, and the elderly due to its potential toxicity. Option C is wrong as repeated applications of lindane should not be used within a short time frame due to the risk of toxicity. Option D is also incorrect as lindane is contraindicated in patients with a history of seizures due to its potential to lower the seizure threshold. In an educational context, it is crucial for healthcare providers to be aware of the appropriate use of medications to ensure patient safety and optimal outcomes. Understanding the indications, contraindications, and potential adverse effects of pharmacological treatments like lindane is essential for providing high-quality care to patients with scabies. Educating healthcare professionals on evidence-based treatment guidelines can help prevent medication errors and promote safe prescribing practices.

Correct Answer: C

Rationale: In the context of diagnosing trichomoniasis, the correct answer is C) Vaginal discharge. Trichomoniasis is a sexually transmitted infection caused by the parasite Trichomonas vaginalis. One of the hallmark symptoms is a frothy, malodorous vaginal discharge that is typically yellow-green in color. This discharge is often accompanied by itching, irritation, and discomfort in the genital area. Option A) Painless, ulcerated vulvar lesion with vaginal discharge is more indicative of genital herpes or syphilis, not trichomoniasis. Option B) Fever, papules, and vaginal discharge with burning are more characteristic of a different STI like chlamydia or gonorrhea. Option D) Dyspareunia and upper abdominal pain are not typically associated with trichomoniasis. From an educational perspective, understanding the specific symptoms associated with different STIs is crucial for accurate diagnosis and appropriate treatment. Nurses and nurse practitioners need to be able to differentiate between various STIs based on presenting symptoms to provide effective care and promote patient health and well-being.

Correct Answer: A

Rationale: In this question, the correct answer is option A) 13-year-old female with a 100° curve. The rationale behind this is that the degree of curvature in scoliosis is a critical factor in determining the severity of the condition and the potential for complications. A curve of 100° is indicative of severe scoliosis, which can lead to significant health issues such as respiratory problems, cardiac issues, and physical deformity. Option B) 17-year-old female with a 100° curve is not the greatest concern because scoliosis progression tends to be more rapid in younger individuals, thus a 13-year-old with the same degree of curvature would be at higher risk. Option C) 12-year-old female with a 50° curve is not the greatest concern as the degree of curvature is less severe compared to option A. Option D) 18-year-old female with a 50° curve is also not the greatest concern because although the age is closer to adulthood, the degree of curvature is still less severe than option A. Educationally, this question highlights the importance of understanding the progression and severity of scoliosis in different age groups and the need for early intervention and monitoring in younger patients with severe curvature to prevent complications and optimize outcomes.

Correct Answer: C

Rationale: In this scenario, the correct answer is C) Inflammatory breast cancer. This type of breast cancer presents with erythema and swelling of the breast, indicating a rapid progression. Inflammatory breast cancer is an aggressive form of breast cancer that typically does not present as a distinct lump but rather as a diffuse swelling and redness of the breast skin. This unique presentation sets it apart from other types of breast cancer. Option A) Paget’s disease is a different condition that affects the skin of the nipple and areola, causing redness, scaling, and itching. It is not typically associated with rapid swelling of the breast. Option B) Invasive ductal carcinoma is the most common type of breast cancer, but it does not usually present with the characteristic erythema and rapid progression seen in inflammatory breast cancer. Option D) Invasive lobular carcinoma is another common type of breast cancer, but it tends to grow in a more subtle, infiltrative pattern without the rapid onset of symptoms like erythema and swelling. Understanding the specific clinical presentations of different types of breast cancer is crucial for healthcare providers involved in breast health assessment and diagnosis. Recognizing the unique features of inflammatory breast cancer can lead to timely intervention and improved outcomes for patients.
