Nursing Elites

1. A client with type 2 diabetes mellitus is prescribed metformin. The nurse should monitor the client for which of the following potential side effects?

• A. Lactic acidosis
• B. Hypokalemia
• C. Hyperglycemia
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A, lactic acidosis. Metformin, a common medication for type 2 diabetes mellitus, can lead to lactic acidosis, particularly in individuals with renal impairment or predisposing factors. Monitoring for signs of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or uneven heart rate, is crucial to prevent serious complications. Choices B, C, and D are incorrect as metformin does not typically cause hypokalemia, hyperglycemia, or weight gain as its primary side effects.

2. 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.

3. The client has been vomiting and has had numerous episodes of diarrhea. Which laboratory test should the nurse monitor?

• A. Serum calcium.
• B. Serum phosphorus.
• C. Serum potassium.
• D. Serum sodium.

Correct answer: C

Rationale: During episodes of vomiting and diarrhea, there is a risk of significant potassium loss, leading to potential electrolyte imbalances. Monitoring serum potassium levels is crucial in this situation to assess and manage any abnormalities promptly. Serum calcium (Choice A) is not typically affected by vomiting and diarrhea. Serum phosphorus (Choice B) levels are not commonly altered by these symptoms. Serum sodium (Choice D) may be affected in severe cases of dehydration, but potassium monitoring is a higher priority due to its potential for rapid depletion in vomiting and diarrhea.

4. The client with DM is being instructed by the nurse about the importance of controlling blood glucose levels. The nurse should emphasize that uncontrolled blood glucose can lead to:

• A. Increased risk of heart disease and stroke.
• B. Improved wound healing.
• C. Reduced need for medication.
• D. Decreased risk of infection.

Correct answer: A

Rationale: The correct answer is A: Increased risk of heart disease and stroke. Uncontrolled blood glucose levels in clients with diabetes mellitus (DM) can lead to cardiovascular complications, such as heart disease and stroke. High blood glucose levels can damage blood vessels over time, increasing the risk of atherosclerosis and cardiovascular events. Choices B, C, and D are incorrect because uncontrolled blood glucose levels do not improve wound healing, reduce the need for medication, or decrease the risk of infection. In fact, uncontrolled blood glucose levels can impair wound healing, require more medications to manage symptoms, and increase the risk of infections due to compromised immune function.

5. An incoherent female client with a history of hypothyroidism is brought to the emergency department by the rescue squad. Physical and laboratory findings reveal hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area. Knowing that these findings suggest severe hypothyroidism, Nurse Libby prepares to take emergency action to prevent the potential complication of:

• A. Thyroid storm.
• B. Cretinism.
• C. Myxedema coma.
• D. Hashimoto's thyroiditis.

Correct answer: C

Rationale: The scenario described with hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area is indicative of myxedema coma, a severe and life-threatening complication of hypothyroidism. Myxedema coma requires immediate emergency treatment to prevent further deterioration. Choice A, thyroid storm, is a complication of hyperthyroidism characterized by an increase in body temperature, heart rate, and blood pressure. Choice B, cretinism, refers to untreated congenital hypothyroidism leading to mental and physical growth retardation. Choice D, Hashimoto's thyroiditis, is an autoimmune condition leading to hypothyroidism but does not present with the acute, life-threatening symptoms described in the scenario.
