1. Which of the following joints normally allows 360-degree circumflexion?

• A. The knee
• B. The shoulder
• C. The elbow
• D. The fingertips

Correct answer: B

Rationale: The correct answer is B: The shoulder. The shoulder joint is a ball-and-socket joint that allows for a wide range of motion, including 360-degree circumflexion. This joint provides flexibility and mobility in various directions. Choice A, the knee joint, primarily allows flexion and extension but does not have a 360-degree circumflexion. Choice C, the elbow joint, is a hinge joint that permits flexion and extension but not circumflexion. Choice D, the fingertips, do not form a specific joint that allows circumflexion; rather, they have joints that enable bending and straightening movements.

2. Your patient has been diagnosed with giant cell arthritis. What medication will this patient most likely be given?

• A. High doses of aspirin
• B. High doses of prednisone
• C. Methotrexate
• D. Albuterol

Correct answer: B

Rationale: High doses of prednisone are commonly prescribed for giant cell arthritis to reduce inflammation. Aspirin is not typically used for this condition. Methotrexate is more commonly used for conditions like rheumatoid arthritis, not giant cell arthritis. Albuterol is a bronchodilator used for respiratory conditions, not for giant cell arthritis.

3. Round off these numbers to the nearest tenth:

• A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
• B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
• C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
• D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7

Correct answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.

4. What is the most common cause of HHNS?

• A. Insulin overdose
• B. Removal of the adrenal gland
• C. Undiagnosed, untreated hyperpituitarism
• D. Undiagnosed, untreated diabetes mellitus

Correct answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

5. While administering penicillin intravenously, you notice that the patient becomes hypotensive with a bounding, rapid pulse rate. What is the first action you should take?

• A. Decrease the rate of the intravenous medication flow.
• B. Increase the rate of the intravenous medication flow.
• C. Call the doctor.
• D. Stop the intravenous flow.

Correct answer: D

Rationale: The correct action to take when a patient becomes hypotensive with a bounding, rapid pulse rate after administering penicillin intravenously is to stop the intravenous flow immediately. This can help prevent further complications by discontinuing the administration of the medication that might be causing the adverse effects. Decreasing or increasing the rate of medication flow may not address the underlying issue of the patient's adverse reaction. While it's important to involve the healthcare provider in such situations, the immediate priority is to halt the administration of the medication.
