1. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.

2. A client with type 1 DM is experiencing signs of hypoglycemia. The nurse should expect which of the following symptoms?

• A. Tachycardia
• B. Polyuria
• C. Flushed skin
• D. Dry mouth

Correct answer: A

Rationale: In a client experiencing hypoglycemia, tachycardia is a common symptom. This occurs due to the release of adrenaline in response to low blood glucose levels, which stimulates the heart to beat faster. Polyuria, the increased production of urine, flushed skin, and dry mouth are not typical symptoms of hypoglycemia. Polyuria is more commonly associated with conditions like diabetes insipidus or uncontrolled diabetes mellitus. Flushed skin and dry mouth are not direct physiological responses to low blood sugar levels.

3. What is the lowest fasting plasma glucose level suggestive of a diagnosis of DM?

• A. 90 mg/dl.
• B. 115 mg/dl.
• C. 126 mg/dl.
• D. 180 mg/dl.

Correct answer: C

Rationale: A fasting plasma glucose level of 126 mg/dl or higher is diagnostic of diabetes mellitus. Choice A (90 mg/dl) is too low to indicate diabetes. Choice B (115 mg/dl) is also below the diagnostic threshold for diabetes. Choice D (180 mg/dl) is above the diagnostic threshold and would indicate uncontrolled diabetes, not the lowest level suggestive of a diagnosis.

4. Clinical manifestations associated with a diagnosis of type 1 DM include all of the following except:

• A. Hypoglycemia.
• B. Hyponatremia.
• C. Ketonuria.
• D. Polyphagia.

Correct answer: B

Rationale: Clinical manifestations of type 1 diabetes mellitus include hypoglycemia, ketonuria, and polyphagia. Hyponatremia is not typically associated with type 1 diabetes mellitus; it is more commonly linked with other conditions such as syndrome of inappropriate antidiuretic hormone secretion (SIADH) or heart failure. Therefore, the correct answer is B: Hyponatremia.

5. Knowing that gluconeogenesis helps to maintain blood glucose levels, a healthcare provider should:

• A. Document weight changes due to fatty acid mobilization.
• B. Evaluate the patient's sensitivity to low room temperatures due to decreased adipose tissue insulation.
• C. Protect the patient from sources of infection due to decreased cellular protein deposits.
• D. Do all of the above.

Correct answer: D

Rationale: Gluconeogenesis is a process where the body synthesizes glucose from non-carbohydrate sources to maintain blood glucose levels. Documenting weight changes due to fatty acid mobilization is important as it can impact the patient's metabolic status. Evaluating the patient's sensitivity to low room temperatures because of decreased adipose tissue insulation is crucial to prevent hypothermia. Protecting the patient from sources of infection due to decreased cellular protein deposits is essential to prevent complications. Therefore, all the options are relevant considerations in managing a patient undergoing gluconeogenesis, making option D the correct answer.
