Reproductive System Exam Questions
1. Which of the following hormones promotes endometrial growth?
- A. LH
- B. FSH
- C. Estrogen
- D. Progesterone
Correct answer: C
Rationale: Estrogen is the hormone responsible for promoting endometrial growth. Estrogen helps thicken the endometrium during the menstrual cycle in preparation for implantation. LH (Choice A) and FSH (Choice B) are involved in regulating the menstrual cycle but do not directly promote endometrial growth. Progesterone (Choice D) is important for maintaining the endometrium after ovulation but is not the primary hormone responsible for promoting its growth.
2. Which of the following is the term used to represent alternative versions of a gene?
- A. Alleles
- B. Binary fission
- C. Heterozygous
- D. Homozygous
Correct answer: A
Rationale: The correct answer is A: Alleles. Alleles are different versions of a gene that can exist at a specific locus on a chromosome. This term specifically refers to the different forms of a gene that can exist. Choices B, C, and D are incorrect because they do not represent alternative versions of a gene. Binary fission is a form of asexual reproduction in single-celled organisms, while heterozygous and homozygous refer to the genetic makeup of an individual rather than alternative versions of a gene.
3. A client is receiving 30 mg of enoxaparin subcutaneously twice a day. In assessing adverse effects of the medication, which serum laboratory value is most important for the nurse to monitor?
- A. Hemoglobin level
- B. Platelet count
- C. Activated partial thromboplastin time (aPTT)
- D. Prothrombin time (PT)
Correct answer: B
Rationale: The correct answer is B: Platelet count. Enoxaparin can cause heparin-induced thrombocytopenia (HIT), making it crucial to monitor the platelet count for signs of thrombocytopenia. Monitoring the platelet count helps in early detection of this serious adverse effect. Choices A, C, and D are less relevant in this context. Hemoglobin level checks are more indicative of bleeding issues rather than thrombocytopenia caused by enoxaparin. Activated partial thromboplastin time (aPTT) and prothrombin time (PT) are less impacted by enoxaparin and are not typically used to monitor for HIT.
4. While caring for a client's postoperative dressing, the nurse observes purulent drainage at the wound. Before reporting this finding to the healthcare provider, the nurse should review which of the client's laboratory values?
- A. White blood cell count
- B. Hemoglobin
- C. Serum creatinine
- D. Culture for sensitive organisms
Correct answer: D
Rationale: Purulent drainage suggests an infection at the wound site. Reviewing the culture and sensitivity results will guide appropriate antibiotic treatment by identifying the causative organisms and their antibiotic sensitivities. Elevated white blood cells indicate infection but do not specify the organism. Creatinine and hemoglobin values are unrelated to wound infections.
5. A client with type 1 DM calls the nurse to report recurrent episodes of hypoglycemia with exercise. Which statement by the client indicates an inadequate understanding of the peak action of NPH insulin and exercise?
- A. The best time for me to exercise is every afternoon.
- B. The best time for me to exercise is right after I eat.
- C. The best time for me to exercise is after breakfast.
- D. The best time for me to exercise is after my morning snack.
Correct answer: A
Rationale: Exercising in the afternoon may coincide with the peak action of NPH insulin, increasing the risk of hypoglycemia. The peak action of NPH insulin typically occurs 4-12 hours after administration, so exercising during this time can further lower blood sugar levels. Choices B, C, and D are better options as they suggest exercising at times that are less likely to overlap with the peak insulin action, reducing the risk of hypoglycemia.
