HESI LPN
HESI Mental Health Practice Exam
1. A client, who is on a 30-day commitment to a drug rehabilitation unit, asks the nurse if he can go for a walk on the grounds of the treatment center. When he is told that his privileges do not include walking on the grounds, the client becomes verbally abusive. Which approach will the nurse take?
- A. Call a staff member to escort the client to his room.
- B. Tell the client to talk to his healthcare provider about his privileges.
- C. Remind the client of the unit rules.
- D. Ignore the client's inappropriate behavior.
Correct answer: C
Rationale: (C) is the correct approach in this situation as it reinforces unit rules, setting clear boundaries and expectations. By reminding the client of the unit rules, the nurse is helping to maintain a safe and structured environment within the drug rehabilitation unit. (A) is unnecessary since the client's behavior does not warrant immediate physical intervention. (B) is not ideal because the client's privileges have already been explained, and suggesting he speak to his healthcare provider may not address the immediate issue. (D) is not appropriate as addressing inappropriate behavior is essential in a therapeutic setting.
2. What is the process in which the double helix of deoxyribonucleic acid (DNA) duplicates?
- A. Amniocentesis
- B. Mitosis
- C. Meiosis
- D. Mutation
Correct answer: B
Rationale: Mitosis is the correct answer because it is the process of cell division in which a cell duplicates its DNA and divides into two identical daughter cells. During mitosis, the DNA is replicated, and each daughter cell receives an identical copy of the genetic material. Amniocentesis is a medical procedure to collect amniotic fluid for prenatal genetic testing and is not related to DNA duplication. Meiosis is a type of cell division that produces gametes with half the genetic material of the parent cell, leading to genetic diversity. Mutation is a permanent alteration in the DNA sequence that can lead to genetic variations but is not the process of DNA duplication.
3. Select a myth or falsehood relating to pain, pain management, and addiction.
- A. Addiction can be accurately predicted.
- B. Withdrawal, drug tolerance, and physical dependence do not indicate addiction.
- C. Pain medications should be avoided in patients with a substance abuse history.
- D. Addiction is signaled by deception and stockpiling by the client.
Correct answer: A
Rationale: The correct answer is A because addiction cannot be accurately predicted. Choices B and C are incorrect. Withdrawal, drug tolerance, and physical dependence are not definitive signs of addiction, and pain medications can be used with patients who have a substance abuse history under careful monitoring. Choice D is incorrect because addiction is not solely signaled by deception and stockpiling; it is a complex condition with various behavioral, physical, and psychological aspects.
4. A client with hypertension is prescribed lisinopril. The nurse should monitor for which potential side effect?
- A. Dry cough
- B. Hyperkalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is A: Dry cough. Lisinopril, an ACE inhibitor, is known to cause a persistent dry cough as a common side effect. Monitoring for this adverse effect is crucial because it may lead to non-adherence to the medication. Hyperkalemia (choice B) is a potential side effect of potassium-sparing diuretics, not ACE inhibitors like lisinopril. Hypernatremia (choice C) refers to elevated sodium levels and is not a common side effect of lisinopril. Hyponatremia (choice D) is a condition characterized by low sodium levels and is not a typical side effect of lisinopril. Therefore, the nurse should focus on assessing the client for a dry cough when taking lisinopril.
5. Dizygotic (DZ) twins share _________ percent of their genes.
- A. 100
- B. 75
- C. 50
- D. 25
Correct answer: C
Rationale: Dizygotic (DZ) twins share approximately 50% of their genes. This is because dizygotic twins, also known as fraternal twins, originate from two separate fertilized eggs and share similar genetic similarity to regular siblings. Choice A (100%) is incorrect because if twins shared 100% of their genes, they would be identical twins (monozygotic). Choice B (75%) is incorrect as it is not the typical genetic similarity seen in dizygotic twins. Choice D (25%) is incorrect as it represents a significantly lower genetic similarity than what is observed in dizygotic twins.
