NCLEX RN Exam Review Answers
1. As a nursing supervisor in a long-term care facility, you prioritize strict infection control prevention measures due to the understanding that the normal aging process weakens the body's defenses. Which theory of aging supports the necessity of strict infection control prevention measures?
- A. The Programmed Longevity Theory
- B. The Immunological Theory of Aging
- C. The Endocrine Theory
- D. The Rate of Living Theory
Correct answer: B
Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.
2. After a lengthy explanation of a medical procedure, the patient asks many questions. The physician answers all of the questions to the best of their ability. The patient then gives consent for treatment. The costly equipment and supplies are put into place, and the patient is prepared. Two minutes before the procedure is to start, the patient begins panicking and changes their mind. Which of the following situations would be the best way to avoid litigation?
- A. Document that the patient originally gave consent and proceed if the benefits of the procedure outweigh the patient's wishes.
- B. Have the patient sign a form stating that they are refusing consent. If they refuse to sign, do not proceed with the procedure.
- C. Repeat the explanation of the procedure until the patient understands that having the procedure done is the best form of treatment. Do not proceed with the procedure.
- D. Do not proceed. Document the patient's refusal, have the patient sign a refusal to consent to treatment. If the patient refuses to sign the form, have a witness available to sign.
Correct answer: D
Rationale: In this scenario, the best course of action to avoid litigation is to respect the patient's right to refuse treatment, especially when changing their mind before the procedure starts. By not proceeding with the treatment, documenting the patient's refusal, and having the patient sign a refusal to consent form, you are following proper ethical and legal procedures. If the patient refuses to sign the form, having a witness available to sign further strengthens the documentation of the patient's decision. This approach ensures that the patient's autonomy and right to make informed decisions about their healthcare are respected. Choices A, B, and C do not prioritize the patient's right to refuse treatment and could potentially lead to legal issues if treatment is carried out against the patient's wishes.
3. One of the complications of complete bed rest and immobility is which of the following?
- A. Plantar flexion
- B. Dorsiflexion
- C. Extension contractures
- D. Adduction contractures
Correct answer: A
Rationale: Plantar flexion, or foot drop, is a common complication of complete bed rest and immobility. This condition occurs due to the weakening of muscles that lift the foot, leading to the foot dragging or being unable to clear the ground during walking. Dorsiflexion refers to moving the foot upwards, which is not a typical complication of immobility. Extension contractures involve the inability to fully extend a joint, while adduction contractures refer to the inability to move a limb away from the body. These types of contractures can also occur with immobility, but they are not specifically associated with foot drop.
4. A patient born in 1955 had hepatitis A infection 1 year ago. According to Centers for Disease Control and Prevention (CDC) guidelines, which action should the nurse include in care when the patient is seen for a routine annual physical exam?
- A. Start the hepatitis B immunization series.
- B. Teach the patient about hepatitis A immune globulin.
- C. Ask whether the patient has been screened for hepatitis C.
- D. Test for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM).
Correct answer: C
Rationale: The correct action for the nurse to include in care when the patient is seen for a routine annual physical exam, according to CDC guidelines, is to ask whether the patient has been screened for hepatitis C. CDC guidelines recommend screening patients born between 1945 and 1965 for hepatitis C due to the high prevalence of undiagnosed cases in this age group. Starting the hepatitis B immunization series is not necessary as the patient already had hepatitis A infection. Teaching the patient about hepatitis A immune globulin is not indicated in this scenario. Testing for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM) is not needed as the patient has already had hepatitis A.
5. Which of the following components is associated with hypertonic dehydration?
- A. Plasma sodium levels above 150 mEq/L
- B. Fluid moves from extracellular space to intracellular space
- C. Water loss is greater than electrolyte loss
- D. Physical signs and symptoms are grossly apparent
Correct answer: C
Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.
