NCLEX PN Exam Cram
1. What is one characteristic of human immunodeficiency virus (HIV)?
- A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
- B. HIV replication occurs intracellularly.
- C. HIV integrates its genetic material into the host cell's DNA.
- D. DNA replication is irrelevant to HIV.
Correct answer: C
Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.
2. A nurse reviews the health history of a client who will be seeing the health care provider to obtain a prescription for a combination oral contraceptive (estrogen and progestin). Which finding in the health history would cause the nurse to determine that the use of a combination oral contraceptive is contraindicated?
- A. The client has type 2 diabetes mellitus.
- B. The client is being treated for hypertension.
- C. The client has been treated for breast cancer.
- D. The client has hyperlipidemia.
Correct answer: C
Rationale: The correct answer is that the client has been treated for breast cancer. Combination oral contraceptives containing estrogen and progestin are contraindicated for women with a history of certain conditions, such as thrombophlebitis, thromboembolic disorders, cerebrovascular disease, coronary artery disease, myocardial infarction, known or suspected breast cancer, known or suspected estrogen-dependent neoplasm, benign or malignant liver tumors, and undiagnosed abnormal genital bleeding. Although having type 2 diabetes mellitus, being treated for hypertension, or having hyperlipidemia are risk factors that require caution when using combination oral contraceptives, they are not absolute contraindications like a history of breast cancer.
3. A child presents to the school nurse with left knee pain after suffering a fall on the playground. Which action should the nurse do first?
- A. Instruct the child to extend the affected knee
- B. Perform range of motion exercises on both knees
- C. Compare the appearance of the left knee to the right knee
- D. Have the child soak the affected knee in warm water
Correct answer: C
Rationale: Comparing the appearance of the left knee to the right knee is the most appropriate initial action as it provides a baseline for assessing any visible differences such as swelling, bruising, or deformities. This comparison helps the nurse identify any acute changes in the affected knee's appearance after the fall. Instructing the child to extend the affected knee (Choice A) may worsen the pain or cause further injury. Performing range of motion exercises on both knees (Choice B) could exacerbate the pain and should be avoided until a proper assessment is done. Having the child soak the affected knee in warm water (Choice D) is not the priority at this stage as assessing for any physical changes is more crucial.
4. A client has been diagnosed with Disseminated Intravascular Coagulation (DIC) and transferred to the medical intensive care unit (ICU) following an acute bleeding episode. In the ICU, continuous Heparin drip therapy is initiated. Which of the following assessment findings indicates a positive response to Heparin therapy?
- A. increased platelet count
- B. increased fibrinogen
- C. decreased fibrin split products
- D. decreased bleeding
Correct answer: B
Rationale: Effective Heparin therapy should halt the process of intravascular coagulation, leading to increased availability of fibrinogen. Heparin interferes with thrombin-induced conversion of fibrinogen to fibrin. Therefore, an increased fibrinogen level indicates a positive response to Heparin therapy. While increased platelet count and decreased bleeding are positive outcomes, the specific indicator for Heparin therapy response is the increase in fibrinogen level. Decreased fibrin split products would also be a positive response, but an increase in fibrinogen directly reflects the impact of Heparin therapy.
5. When choosing a needle gauge for an intramuscular injection in a 12-year-old boy, which of the following gauges would you choose?
- A. 27 gauge
- B. 25 gauge
- C. 22 gauge
- D. 20 gauge
Correct answer: C
Rationale: The correct answer is 22 gauge. A 22-gauge needle is recommended for school-age children, toddlers, and adolescents due to their muscle mass and tolerance. In infants, a smaller gauge (23-25) is preferred as their muscles are less developed and more sensitive. Choice A, 27 gauge, is too thin for an intramuscular injection in a 12-year-old boy. Choice B, 25 gauge, is more suitable for infants than for a 12-year-old. Choice D, 20 gauge, is too thick and not typically used for intramuscular injections in children.
