Correct Answer: D

Rationale: The described findings of a triangular thickening of the bulbar conjunctiva across the outer surface of the cornea are characteristic of a pterygium. A pterygium is a benign growth of conjunctival tissue that extends onto the cornea. It is often associated with chronic exposure to ultraviolet light and typically occurs on the nasal side of the eye. Pterygiums are usually asymptomatic but can cause irritation, redness, and foreign body sensation in some cases. Surgical removal may be considered if the pterygium causes significant symptoms or affects vision.

Correct Answer: B

Rationale: Ascites is the abnormal accumulation of fluid in the abdominal cavity. When ascites is present, dullness is typically heard on percussion due to the fluid in the abdomen. This dullness does not shift with changes in the patient's position.
Therefore, the finding of dullness which remains despite a change in position would argue for the presence of ascites. The other choices (A, C,
D) describe findings that are more consistent with gaseous distention rather than ascites.

Correct Answer: C

Rationale: The statement that a high proportion of breast masses are detected by breast self-examination is true. Studies have shown that only a small percentage of breast cancers are actually detected by women themselves through self-examination. In fact, most breast cancers are detected through clinical breast exams and mammograms.
Therefore, while it is still important for women to be breast aware and report any changes they notice to their healthcare provider, the practice of routine breast self-examinations is no longer universally recommended. Instead, the focus has shifted towards regular clinical breast exams and mammograms based on individual risk factors.

Correct Answer: C

Rationale: A right homonymous hemianopsia refers to a visual field defect in which the patient is unable to see objects in the right half of the visual field in both eyes. In the case described, the stroke patient is unable to see your fingers on his entire right side with either eye covered, which is consistent with a right homonymous hemianopsia. This type of visual field defect typically occurs as a result of damage to the optic tract or optic radiation on one side of the brain, which affects the processing of visual information from the opposite visual field. It is important to note that bitemporal hemianopsia, right temporal hemianopsia, and binasal hemianopsia involve different patterns of visual field loss and are not fitting descriptions for the presented scenario.

Correct Answer: A

Rationale: It is crucial to keep the patient's torso at a 45-degree angle when measuring the jugular venous pressure (JVP). This position allows the internal jugular vein to partially collapse, ensuring accurate observation of the pulsations. Keeping the patient at a 45-degree angle provides a standardized position for JVP measurement and helps avoid errors in assessment.
