Question 1 of 5
In general, chemotherapy is discouraged in patients with a poor performance status unless which condition exists?
Correct Answer: C
Rationale: Chemotherapy in poor performance status is justified only if it significantly improves quality of life (e.g., symptom palliation), outweighing risks. Legal demands or trial data alone don't override clinical judgment.
Question 2 of 5
61 yo woman. Weakness and polyuria. Hx PUD(antacids/baking soda), COPD(40 pk/yr), PE frail and dry. Labs: Hematocrit 41, Na 152, K 3.0, Cl 100, HCO3 40, BUN 98, creatinine 7.1, Ca 14.4, PO4 6.3, 1, 25-VitD low, PTH 16 pg/ml. UA NL.US kidneys. This presentation is MOST consistent with?
Correct Answer: D
Rationale: Hypercalcemia, metabolic alkalosis, and renal insufficiency in a patient using excessive antacids are hallmark features of milk-alkali syndrome.
Question 3 of 5
Which type of synovial fluid is seen in thyroid disease?
Correct Answer: D
Rationale: Thyroid disease, particularly hypothyroidism, is associated with Group I synovial fluid, characterized by non-inflammatory properties. In this format, 'Group I' (E) is shifted to D.
Question 4 of 5
A patient who reports dizziness and who has absent P waves, wide QRS complexes, and a heart rate of 38 beats/min on an ECG is most likely in which rhythm?
Correct Answer: C
Rationale: A ventricular escape rhythm originates in the Purkinje fibers, has a rate of 15 to 40 beats/minute, and is characterized by a wide QRS complex. An important clue to identifying escape rhythms is the absence of normal P waves and PR intervals. The rhythm involved in third-degree heart block includes regularly occurring P waves. Junctional tachycardia has a heart rate between 70 to 140 beats/minute. P waves are preceding, following, or buried in the QRS complex. Sinus bradycardia has a normal pattern on the ECG, but with a rate of less than 60 beats/minute.
Question 5 of 5
A patient taking Digoxin is experiencing severe bradycardia, nausea, and vomiting. A lab draw shows that their Digoxin level is 4 ng/mL. What medication do you anticipate the physician to order for this patient?
Correct Answer: C
Rationale: Digoxin toxicity (level >2 ng/mL) causes bradycardia and GI symptoms; Digibind (C) is the antidote to reverse toxicity.
