Correct Answer: A

Rationale: The correct answer is A: 'Sweating and trembling.' These are classic early signs of hypoglycemia in a diabetic patient. Sweating occurs due to the activation of the sympathetic nervous system in response to low blood sugar levels, while trembling is a result of the body's attempt to increase muscle activity to raise blood sugar levels. Confusion and irritability (Choice B) are more advanced signs of hypoglycemia that occur if the condition is not treated promptly. Dizziness and increased heart rate (Choice C) can also occur but are not as specific and early as sweating and trembling. Nausea and vomiting (Choice D) are more commonly associated with other conditions or severe hypoglycemia, rather than being early signs.

Correct Answer: B

Rationale: The correct answer is B because imagining oneself in a calm place is a relaxation technique that helps reduce anxiety. Walking, meditating every other week, or cutting back on caffeine intake may have their benefits, but they are not as directly related to the immediate management of anxiety as the visualization technique described in option B.

Correct Answer: D

Rationale: The correct answer is 'D: All of the above.' Edema, hypertension, and shortness of breath are key signs of fluid overload, particularly common in patients with heart failure. Edema refers to the swelling caused by excess fluid trapped in the body's tissues, hypertension can be a result of fluid volume overload, and shortness of breath can occur due to fluid accumulation in the lungs. Therefore, all these signs collectively indicate fluid overload in a patient. Choices A, B, and C are incorrect individually as each alone may not necessarily indicate fluid overload, but when seen together, they strongly suggest fluid volume excess in the body.

Correct Answer: A

Rationale: Low birth weight increases a child's vulnerability to physical maltreatment due to additional care needs. Advanced maternal age (choice B) is not directly linked to an increased risk of physical maltreatment. Single parenthood (choice C) is not a characteristic that inherently increases the risk of physical maltreatment. Premature birth (choice D) is not listed as a characteristic that directly increases a child's risk of physical maltreatment.

Correct Answer: B

Rationale: The nurse should question the dosage of haloperidol as it is typically administered in milligrams (mg) and not milliliters (mL). The dosage should be expressed in a standardized unit for accuracy and to prevent medication errors. Frequency, timing of doses, and route are also important components of a prescription, but in this case, the nurse should focus on the unusual dosage form.
