1. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.

2. The healthcare provider is assessing a client with Addison's disease. Which of the following symptoms is consistent with this condition?

• A. Hypertension
• B. Hyperglycemia
• C. Hyperpigmentation
• D. Weight gain

Correct answer: C

Rationale: Hyperpigmentation is a characteristic symptom of Addison's disease. In Addison's disease, there is a decrease in cortisol production, leading to an increase in adrenocorticotropic hormone (ACTH) secretion by the pituitary gland. Excess ACTH can stimulate melanocytes, resulting in hyperpigmentation. Choices A, B, and D are not typically associated with Addison's disease. Hypertension is more commonly associated with conditions involving excess cortisol production, such as Cushing's syndrome. Hyperglycemia may occur in diabetes mellitus but is not a hallmark of Addison's disease. Weight loss, rather than weight gain, is a common symptom of Addison's disease due to decreased cortisol levels.

3. Nurse Wayne is aware that a positive Chvostek's sign indicates:

• A. Hypocalcemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypermagnesemia

Correct answer: A

Rationale: A positive Chvostek's sign indicates hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching due to increased neuromuscular irritability from low calcium levels. Hyponatremia (Choice B) is characterized by low sodium levels, but it does not present with Chvostek's sign. Hypokalemia (Choice C) is low potassium levels, and hypermagnesemia (Choice D) is high magnesium levels, neither of which are associated with Chvostek's sign.

4. The healthcare professional is educating a client with Cushing's syndrome about dietary management. Which of the following instructions should the healthcare professional include?

• A. Increase sodium intake
• B. Limit protein intake
• C. Limit calcium intake
• D. Increase potassium intake

Correct answer: D

Rationale: For clients with Cushing's syndrome, they are at risk of developing hypokalemia due to increased excretion of potassium. Therefore, it is essential to advise them to increase their potassium intake. Choices A, B, and C are incorrect because: A) Increasing sodium intake can worsen fluid retention and hypertension common in Cushing's syndrome. B) Limiting protein intake is not necessary unless there are specific kidney issues that require protein restriction. C) Limiting calcium intake is not typically recommended unless there are underlying conditions such as hypercalcemia.

5. A nurse manager in the emergency department considers policy changes in the organization and changes in the community, and tries to predict how these may impact the functioning of the unit. Which of the following decisional activities best describes this manager’s actions?

• A. Resource allocation
• B. Monitoring
• C. Job analysis and redesign
• D. Planning for the future

Correct answer: D

Rationale: The correct answer is D: Planning for the future. In this scenario, the nurse manager is engaging in decisional activities related to planning for the future. This involves analyzing potential impacts of policy changes and community shifts on the unit's functioning and making decisions based on predictions and foresight. Option A, resource allocation, focuses on distributing resources effectively. Option B, monitoring, involves observing and assessing current activities. Option C, job analysis and redesign, pertains to evaluating and restructuring roles and responsibilities within the unit, which is not the primary focus of the scenario provided.
