1. A healthcare professional is reviewing a client's laboratory report and notes that the serum calcium level is 4.0 mg/dL. The healthcare professional understands that which condition most likely caused this serum calcium level?

• A. Prolonged bed rest
• B. Renal insufficiency
• C. Hyperparathyroidism
• D. Excessive ingestion of vitamin D

Correct answer: A

Rationale: Prolonged bed rest can lead to hypocalcemia due to decreased mobility and bone resorption. In this scenario, the low serum calcium level of 4.0 mg/dL is likely a result of decreased bone activity and calcium release due to prolonged bed rest. Renal insufficiency would more likely lead to hypercalcemia due to impaired excretion of calcium by the kidneys. Hyperparathyroidism is characterized by increased calcium levels as a result of excess parathyroid hormone. Excessive ingestion of vitamin D can cause hypercalcemia by increasing intestinal absorption of calcium.

2. 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.

3. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

4. The healthcare provider provides instructions to a client with a low magnesium level about the foods that are high in magnesium and tells the client to consume which foods? Select one that does not apply.

• A. Peas
• B. Oranges
• C. Apples
• D. Peanut butter

Correct answer: B

Rationale: Oranges are not high in magnesium. The other choices, such as peas, are good sources of magnesium. Peas, along with cauliflower and canned white tuna, are foods rich in magnesium. Oranges, although healthy, are not known for their high magnesium content.

5. What is the primary focus of primary healthcare?

• A. Emergency care
• B. Preventive care
• C. Specialized treatment
• D. Hospital-based services

Correct answer: B

Rationale: The correct answer is B: Preventive care. Primary healthcare emphasizes preventive care, which includes promoting overall health, preventing diseases, and providing early intervention to avoid the progression of illnesses. Emergency care (choice A) is focused on immediate medical attention for urgent health situations but is not the primary focus of primary healthcare. Specialized treatment (choice C) refers to care provided by specialists for specific health conditions, which is not the main focus of primary healthcare. Hospital-based services (choice D) involve inpatient care provided in a hospital setting, which is not the primary focus of primary healthcare that aims to provide comprehensive and accessible care at the community level.
