HESI Mental Health Practice Questions
1. A client on the psychiatric unit appears to imitate a certain nurse on the unit. The client seeks out this particular nurse and imitates her mannerisms. Which defense mechanism does the nurse recognize in this client?
- A. Sublimation.
- B. Identification.
- C. Introjection.
- D. Repression.
Correct answer: B
Rationale: Identification is the correct answer. It is a defense mechanism where an individual unconsciously models themselves after someone they admire or feel close to. In this scenario, the client is imitating the nurse's mannerisms, indicating identification. Sublimation involves channeling unacceptable impulses into socially acceptable activities. Introjection is the internalization of external attitudes or voices, while repression involves suppressing unwanted thoughts or desires.
2. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client’s right leg?
- A. Dorsiflexes the right foot and left foot on command
- B. A 3 by 5 cm ecchymosis area on the right calf
- C. Right calf is 3 cm larger in circumference than the left calf
- D. Bilateral lower extremities have 3+ pitting edema
Correct answer: C
Rationale: The correct answer is C because a significant difference in calf circumference between the legs is a classic sign of DVT. This is due to the obstruction of blood flow in the deep veins of the leg, leading to swelling in the affected limb. Choices A, B, and D are not typical findings of DVT. Choice A describes a neurological response, choice B indicates a bruise on the right calf, and choice D describes pitting edema in both lower extremities, which are not specific signs of DVT.
3. A cerebrovascular accident patient is placed on a ventilator. The client’s daughter arrives with a durable power of attorney and a living will that indicates no extraordinary life-saving measures. What action should the nurse take?
- A. Refer to the risk manager
- B. Notify the healthcare provider
- C. Discontinue the ventilator
- D. Review the medical record
Correct answer: B
Rationale: The correct action for the nurse to take is to notify the healthcare provider. In this situation, involving the healthcare provider ensures appropriate review and adherence to legal and ethical standards based on the living will and durable power of attorney. Referring to the risk manager may not be directly related to the immediate decision-making process regarding the ventilator. Discontinuing the ventilator without proper authorization from the healthcare provider could lead to legal and ethical implications. Reviewing the medical record alone may not provide guidance on how to proceed with the specific instructions from the living will and durable power of attorney.
4. An older male client is admitted to the mental health unit with a sudden onset of global disorientation and is continuously conversing with his mother, who died 50 years ago. The nurse reviews the multiple prescriptions the client is currently taking and assesses his urine specimen, which is cloudy, dark yellow, and has a foul odor. These findings suggest that this client is experiencing which condition?
- A. Psychotic episode
- B. Dementia
- C. Delirium
- D. Depression
Correct answer: C
Rationale: The correct answer is C, delirium. The sudden onset of global disorientation along with cloudy, dark yellow urine with a foul odor are indicative of delirium. Delirium is an acute condition characterized by a fluctuating disturbance in awareness and cognition. In this case, the symptoms are suggestive of an underlying physiological cause, such as infection or medication side effects. Choice A, psychotic episode, is less likely as the symptoms are more in line with delirium than a primary psychotic disorder. Choice B, dementia, is a chronic and progressive condition, not typically presenting with sudden onset disorientation. Choice D, depression, does not align with the acute cognitive changes and urine abnormalities described in the scenario.
5. When assessing a client's skin as part of a comprehensive physical examination, what finding should a nurse expect?
- A. Capillary refill less than 3 seconds
- B. 1+ pitting edema in both feet
- C. Pale nail beds in both hands
- D. Thick skin on the soles of the feet
Correct answer: A
Rationale: The correct answer is A: Capillary refill less than 3 seconds. This finding is considered normal and indicates good peripheral perfusion. Pitting edema (choice B) and pale nail beds (choice C) are abnormal findings that may suggest underlying health issues. Thick skin on the soles of the feet (choice D) is not an expected normal finding during a skin assessment and could be indicative of a callus or other skin condition.
