Mental Health HESI Practice Questions

Correct Answer: D

Rationale: (D) provides the most validation for suspecting child abuse. The parent's explanation (subjective data) that the child was burned in a house fire is incompatible with the objective data observed by the nurse (small, round burns on the legs and trunk). (A) relies on subjective data, and the child's explanation might not accurately reflect the situation due to various factors like age or fear. The apparent lack of concern from the parents (B) is inconclusive as the nurse's interpretation of their reaction could be subjective. While parental anxiety (C) could hint at potential child abuse, it's important to note that most parents would naturally be anxious about their child's hospitalization, making it a less definitive indicator compared to the inconsistency in the explanation provided by the parents in option (D).

Correct Answer: C

Rationale: The correct answer is C. PET scans are primarily used to detect and observe the metabolic activity in various parts of the brain. This helps in diagnosing conditions related to brain function, such as tumors, brain disorders, and overall brain activity. Choices A, B, and D are incorrect because PET scans focus on metabolic activity and functions in the brain rather than solely indicating the presence of tumors, outlining brain structures, or showing biochemical levels of neurotransmitters.

Correct Answer: A

Rationale: Determining if the client has access to a weapon is critical for immediate safety and to prevent potential harm.

Correct Answer: A

Rationale: The correct answer is A: Decreased thyroid stimulating hormone level. Hyperthyroidism causes an increased level of serum thyroid hormones (T3 and T4), which inhibit the release of TSH. In this case, a decreased TSH level can indicate hyperthyroidism, which can present with manic behavior. Elevated liver function profile (B) is not directly related to the manic phase of bipolar disorder. Increased white blood cell count (C) typically indicates an infection or inflammation, not directly related to the manic phase. Decreased hematocrit and hemoglobin levels (D) may suggest anemia but are not as crucial in the context of a manic phase of bipolar disorder.

Correct Answer: A

Rationale: In a situation where a client is displaying aggression and agitation, the immediate priority of care for the nurse is to ensure safety for the client and others on the unit. Providing a safe environment and implementing calming measures take precedence over other interventions. Option A is the correct choice as it addresses the crucial need for safety in a potentially volatile situation. Options B, C, and D, although important, do not address the primary concern of ensuring safety for all individuals involved.
