1. A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?

A. Prominent U waves
B. Prolonged PR interval
C. Depressed ST segment
D. Widened QRS complexes

Correct answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

2. 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.

3. 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.

4. Which of the following ethical principles is involved when a healthcare provider allows a patient to refuse treatment?

A. Autonomy
B. Nonmaleficence
C. Beneficence
D. Justice

Correct answer: A

Rationale: The correct answer is A: Autonomy. Autonomy is the ethical principle that respects an individual's right to make their own decisions, including the right to refuse treatment. This principle acknowledges the patient's self-governance and independence in making choices about their own healthcare. Choice B, Nonmaleficence, refers to the ethical principle of doing no harm and ensuring patient safety. Choice C, Beneficence, involves promoting the patient's well-being and acting in their best interest. Choice D, Justice, pertains to fairness and equitable distribution of healthcare resources.

5. A male client with type 1 diabetes mellitus asks the nurse about taking an oral antidiabetic agent. Nurse Jack explains that these medications are only effective if the client:

A. Prefers to take insulin orally.
B. Has type 2 diabetes.
C. Has type 1 diabetes.
D. Is pregnant and has type 2 diabetes.

Correct answer: B

Rationale: Oral antidiabetic agents are specifically designed for type 2 diabetes mellitus. Type 1 diabetes requires insulin therapy as the primary treatment due to the absence of endogenous insulin production. Therefore, these medications are not effective for individuals with type 1 diabetes like the male client in this scenario. Choice A is incorrect as oral antidiabetic agents are not about preference but rather about treatment efficacy. Choice D is incorrect as being pregnant does not impact the effectiveness of oral antidiabetic agents; they are primarily indicated for type 2 diabetes.
