Nokea
A 12-year-old presents to the clinic with his father for evaluation of a painful lump in the left eye. It started this morning. He denies any trauma or injury. There is no visual disturbance. Upon physical examination, there is a red raised area at the margin of the eyelid that is tender to palpation; no tearing occurs with palpation of the lesion. Based on this description, what is the most likely diagnosis?
- A. Dacryocystitis
- B. Chalazion
- C. Hordeolum
- D. Xanthelasma
Correct Answer: C
Rationale: The correct answer is C: Hordeolum. A hordeolum, also known as a stye, presents as a red raised tender area at the margin of the eyelid. In this case, the absence of tearing upon palpation of the lesion suggests it is localized to the eyelid itself. Dacryocystitis (choice A) involves the lacrimal sac and would present with tearing. A chalazion (choice B) is a painless nodule on the eyelid, unlike the tender lesion described here. Xanthelasma (choice D) is characterized by yellowish plaques on the eyelids, not a red raised tender area.

Mr. Kruger is an 84-year-old who presents with a smooth lower abdominal mass in the midline which is minimally tender. There is dullness to percussion up to 6 centimeters above the symphysis pubis. What does this most likely represent?
- A. Sigmoid mass
- B. Tumor in the abdominal wall
- C. Hernia
- D. Enlarged bladder
Correct Answer: D
Rationale: Rationale for D (Enlarged bladder): The presentation of a smooth lower abdominal mass that is minimally tender and associated with dullness to percussion above the symphysis pubis suggests an enlarged bladder. This is a common finding in elderly individuals due to various reasons such as urinary retention or bladder outlet obstruction. The location and characteristics of the mass align with an enlarged bladder.
Summary of other choices:
A: Sigmoid mass - Unlikely as sigmoid mass typically presents with different characteristics such as irregular shape and may not cause dullness to percussion above the symphysis pubis.
B: Tumor in the abdominal wall - Less likely as tumors in the abdominal wall would have a different presentation and wouldn't be associated with urinary symptoms.
C: Hernia - Less likely as hernias typically manifest with a bulge that can be reduced and may not cause dullness to percussion above the symphysis pubis.
You are performing a cardiac examination on a patient with shortness of breath and palpitations. You listen to the heart with the patient sitting upright, then have him change to a supine position, and finally have him turn onto his left side in the left lateral decubitus position. Which of the following valvular defects is best heard in this position?
- A. Aortic
- B. Pulmonic
- C. Mitral
- D. Tricuspid
Correct Answer: C
Rationale: The correct answer is C: Mitral valve defect. This is because the mitral valve is best heard in the left lateral decubitus position. In this position, the heart rotates, bringing the mitral valve closer to the chest wall, making it easier to auscultate any abnormalities such as murmurs. Aortic (A), pulmonic (B), and tricuspid (D) valve defects are not typically better heard in the left lateral decubitus position, so they are incorrect choices.
A 40-year-old female, the overall texture of the breast is soft, with an uneven contour bilaterally. The NP informs the patient that:
- A. Warrants a mammogram
- B. Is considered normal
- C. May be suggestive of fibroadenoma
- D. May indicate cystic breast
Correct Answer: B
Rationale: Step-by-step rationale:
1. The patient is 40 years old, which is within the age range for routine screening mammograms.
2. The description of soft, uneven breasts is typical of normal breast tissue variations.
3. Given the patient's age and the benign characteristics described, no further investigation is needed.
Summary of other choices:
A: Warrants a mammogram - Not necessary as the breast characteristics described are normal for the patient's age.
C: May be suggestive of fibroadenoma - Fibroadenomas typically present as firm, well-defined lumps, not soft and uneven breasts.
D: May indicate cystic breast - Cystic breasts may feel lumpy or tender, but the overall texture is not described as soft and uneven.
In which of the following patients is chemical or surgical castration likely to prolong survival?
- A. A 78-year-old man with advanced dementia and prostate cancer metastatic to the bone.
- B. A 78-year-old man who had a radical prostatectomy 10 years earlier and now has a PSA level of 5.7 ng/mL. A year ago it was 0.1 ng/mL. A bone scan is negative and an abdomen-pelvis computed tomography (CT) is negative.
- C. A 78-year-old man who had a radical prostatectomy and external beam radiation therapy 10 years earlier now has a PSA level of 24.5 ng/mL. A CT scan of the pelvis shows an enlarged pelvic lymph node, and a bone scan is positive in the pelvis.
- D. A 78-year-old man with prostate cancer limited to the prostate with a Gleason score of 6.
Correct Answer: C
Rationale: The correct answer is C. In this scenario, the patient had a radical prostatectomy and external beam radiation therapy, indicating aggressive treatment. Despite this, the PSA level is high (24.5 ng/mL), suggesting biochemical recurrence and possible metastasis. The positive bone scan and enlarged pelvic lymph node indicate disease progression beyond the prostate. Chemical or surgical castration, such as androgen deprivation therapy, can help delay disease progression and prolong survival by reducing the levels of testosterone that fuel prostate cancer growth.
Summary:
A: In advanced dementia and metastatic bone disease, castration is unlikely to impact survival as the disease is already advanced.
B: A rising PSA level post-radical prostatectomy with negative imaging indicates biochemical recurrence, but without evidence of metastasis, making castration less beneficial.
D: Prostate cancer limited to the prostate with a Gleason score of 6 is low risk and may not benefit significantly from castration as it is less likely to progress rapidly.
Which is a true statement about varicose veins?
- A. They are due to congenital valve deformities
- B. They are usually diagnosed on clinical presentation
- C. They are not affected by pregnancy
- D. They are more symptomatic during ovulation
Correct Answer: B
Rationale: The correct answer is B because varicose veins are usually diagnosed based on clinical presentation, such as visible, bulging veins and symptoms like pain or swelling. This is because varicose veins are often easily visible and cause noticeable symptoms.
A: Varicose veins are not typically due to congenital valve deformities but rather develop over time due to weakened vein walls and valves.
C: Varicose veins can be affected by pregnancy due to hormonal changes and increased pressure on the veins.
D: Varicose veins may not necessarily be more symptomatic during ovulation; symptoms can vary based on individual factors.
