HESI LPN
HESI Fundamentals Exam
1. A client is expressing anger over his diagnosis of colorectal cancer. Which of the following actions should the nurse take?
- A. Discuss the risk factors for colorectal cancer.
- B. Focus teaching on addressing the client's anger and emotional response.
- C. Provide the client with emotional support and reassurance about his feelings.
- D. Reassure the client that this is an expected response to grief.
Correct answer: D
Rationale: The correct answer is D. During the anger stage of grief, it is essential for the nurse to reassure the client that anger is a normal reaction to a cancer diagnosis. This validation of the client's emotions can help in providing emotional support. Choice A is incorrect because discussing risk factors for colorectal cancer does not address the client's current emotional state. Choice B is incorrect because focusing teaching on the client's future management does not directly address the client's need for emotional support in the present. Choice C is incorrect because providing written information about loss and grief phases is not as immediately comforting as directly reassuring the client about his feelings of anger.
2. What determines a child’s sex?
- A. Presence of teratogens at the time of conception.
- B. Sex chromosome received from the mother.
- C. Presence of teratogens at the time of ovulation.
- D. Sex chromosome received from the father.
Correct answer: D
Rationale: The correct answer is the sex chromosome received from the father. The father contributes either an X or Y chromosome, which determines the child's sex. This occurs at the moment of fertilization when the sperm carrying either an X (resulting in a female) or Y (resulting in a male) chromosome fertilizes the egg. Choices A, B, and C are incorrect because the presence of teratogens at the time of conception or ovulation does not determine the child's sex. While the sex chromosome received from the mother is important, it is the father's contribution that ultimately determines the child's sex.
3. A client is preparing to administer methylergonovine 0.2 mg orally to a client who is 2 hr postpartum and has a boggy uterus. For which of the following assessment findings should the nurse withhold the medication?
- A. Blood pressure 142/92 mm Hg
- B. Urine output 100 mL in 1 hr
- C. Pulse 58/min
- D. Respiratory rate 14/min
Correct answer: A
Rationale: The correct answer is A. Methylergonovine can increase blood pressure, so it should be withheld if the client has hypertension. A blood pressure reading of 142/92 mm Hg indicates hypertension and is a contraindication for administering methylergonovine. Choices B, C, and D are within normal limits and not contraindications for administering this medication. Urine output, pulse rate, and respiratory rate are not factors that determine the appropriateness of administering methylergonovine in this situation.
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. What are neurotransmitters?
- A. Chemical messengers that cause brain cells to turn on or off.
- B. Areas of the brain that are responsible for controlling emotions.
- C. Clumps of cells that alert the other brain cells to receive messages.
- D. Web-like structures that provide connections among parts of the brain.
Correct answer: A
Rationale: Neurotransmitters are chemicals in the brain that act as messengers between neurons, influencing various psychological functions. Choice A correctly defines neurotransmitters by stating that they are chemical messengers that cause brain cells to turn on or off. This is the function of neurotransmitters in transmitting signals between neurons. Choices B, C, and D are incorrect because they do not accurately describe neurotransmitters and their role in the brain.
