Correct Answer: C

Rationale: Exercise for 30 minutes most days of the week is recommended for clients with gestational diabetes mellitus, as it improves insulin sensitivity, helps control blood glucose levels, and supports overall health.
Choice A is wrong because while monitoring blood glucose is essential, the frequency (e.g., four times daily) depends on the provider's plan and the client's condition; the nurse should specify the prescribed schedule.
Choice B is wrong because limiting carbohydrates to 50% of daily calories is not a standard recommendation; carbohydrate intake should be individualized (typically 40-50% of calories) and balanced with protein and fats, as advised by a dietitian.
Choice D is wrong because oral hypoglycemic medications are not first-line for gestational diabetes; insulin is preferred if diet and exercise are insufficient, and oral medications like metformin may be considered in specific cases under provider guidance.

Correct Answer: A

Rationale: An elevated antinuclear antibody (AN
A) titer is a hallmark finding in systemic lupus erythematosus, present in over 95% of clients, indicating autoimmune activity.
Choice B is incorrect because the erythrocyte sedimentation rate (ESR) is typically elevated in SLE due to inflammation, not decreased.
Choice C is incorrect because complement levels (C3, C4) are often decreased in SLE due to immune complex formation, not normal.
Choice D is incorrect because rheumatoid factor may be positive in some SLE clients, but it is not specific to SLE and is more associated with rheumatoid arthritis.

Correct Answer: B

Rationale: Insomnia is a common adverse effect of sertraline, an SSRI, due to its stimulating effect on serotonin levels, and should be monitored, as it may require dose adjustment or bedtime avoidance.
Choice A is incorrect because sertraline is more likely to cause weight gain, not weight loss, over time.
Choice C is incorrect because hypotension is not a common side effect; orthostatic hypotension may occur but is less frequent.
Choice D is incorrect because bradycardia is not typically associated with sertraline; tachycardia may occur with anxiety or overstimulation.

Correct Answer: A

Rationale: Absence seizures are brief, sudden lapses of consciousness that usually last a few seconds. They are more common in children than in adults.
Choice B is wrong because absence seizures typically last less than 15 seconds, not 30 to 60 seconds.
Choice C is wrong because absence seizures have a sudden onset, not a gradual one.
Choice D is wrong because absence seizures do not have an aura prior to onset. An aura is a warning sign that some people experience before a seizure, such as a strange feeling, smell, or vision.

Correct Answer: A

Rationale: A WBC count of 2,500/mm3 is below the normal range (5,000-10,000/mm3) and indicates leukopenia, a common side effect of chemotherapy that increases infection risk, requiring immediate reporting to the provider for potential interventions like growth factors or antibiotics.
Choice B is wrong because a hemoglobin of 12 g/dL is within the normal range for females (12-16 g/dL) and does not require reporting.
Choice C is wrong because a platelet count of 150,000/mm3 is within the normal range (150,000-400,000/mm3) and does not indicate thrombocytopenia.
Choice D is wrong because a potassium level of 4.0 mEq/L is within the normal range (3.5-5.0 mEq/L) and does not require reporting.
