ATI Pathophysiology Exam
1. A woman is being treated with clomiphene citrate for the treatment of infertility. She states to the nurse that she has seen an increase in vaginal discharge. The nurse knows that this effect is related to:
- A. Increased blood flow to the vaginal area.
- B. Increased cervical mucus production.
- C. Increased production of vaginal secretions.
- D. Increased lubrication in the vaginal canal.
Correct answer: C
Rationale: The correct answer is C: 'Increased production of vaginal secretions.' Clomiphene citrate affects cervical mucus production, leading to an increase in vaginal secretions. This effect is beneficial for fertility as it helps create a more hospitable environment for sperm transport. Choice A, 'Increased blood flow to the vaginal area,' is incorrect as the increase in vaginal discharge is primarily due to changes in cervical mucus. Choice B, 'Increased cervical mucus production,' is partially correct but does not fully explain the increase in vaginal secretions. Choice D, 'Increased lubrication in the vaginal canal,' is not directly related to the effect seen with clomiphene citrate treatment for infertility.
2. When reviewing the purpose/action of neurotransmitters as they interact with different receptors, the nursing instructor gives an example using acetylcholine. When acetylcholine is released at the sinoatrial node in the right atrium of the heart, it is:
- A. positively charged.
- B. inhibitory.
- C. overstimulated.
- D. dormant.
Correct answer: B
Rationale: Acetylcholine acts as an inhibitory neurotransmitter at the sinoatrial node. It slows down the heart rate by decreasing the firing rate of the sinoatrial node, which serves as the heart's natural pacemaker. Neurotransmitters do not have a charge, so choice A is incorrect. Choice C is wrong as overstimulation is not a characteristic of acetylcholine at the sinoatrial node. Choice D is also incorrect because acetylcholine actively influences heart rate regulation when released at the sinoatrial node.
3. In the ED, a homeless client is brought in with severe hypothermia. The police officers also state that they found a 'bottle of booze' on the sidewalk next to him. This puts the nurse on high alert since alcohol contributes to hypothermia by:
- A. interfering with the appetite center in the brain, causing the person to not respond to hunger cues.
- B. causing the person to have less insulation from body fat.
- C. dulling mental awareness, impairing judgment to seek shelter.
- D. increasing the basal metabolic rate, leading to faster depletion of ATP.
Correct answer: C
Rationale: Alcohol impairs judgment and dulls mental awareness, making a person less likely to seek shelter when experiencing hypothermia. This impaired judgment can lead to risky behaviors that exacerbate the effects of cold exposure. Choice A is incorrect because alcohol does not directly interfere with the appetite center in the brain to the extent described. Choice B is incorrect as alcohol consumption does not directly impact the amount of body fat present. Choice D is incorrect because alcohol does not increase the basal metabolic rate but rather slows it down.
4. A patient with a history of breast cancer is being prescribed tamoxifen (Nolvadex). What should the nurse include in the patient education?
- A. Tamoxifen may increase the risk of venous thromboembolism.
- B. Tamoxifen may decrease the risk of osteoporosis.
- C. Tamoxifen may cause hot flashes and other menopausal symptoms.
- D. Tamoxifen may cause weight gain and fluid retention.
Correct answer: A
Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism. Patients should be educated about signs and symptoms of blood clots, such as swelling, pain, or redness in the legs. Choices B, C, and D are incorrect because tamoxifen is not associated with decreasing the risk of osteoporosis, causing hot flashes and menopausal symptoms, or causing weight gain and fluid retention.
5. What causes the appearance of a barrel chest in clients with emphysema?
- A. Peripheral edema
- B. Bacterial infections in the lungs
- C. Air trapping in the alveoli
- D. Muscle atrophy of the diaphragm
Correct answer: C
Rationale: The correct answer is C: Air trapping in the alveoli. A barrel chest in emphysema results from the hyperinflation of the lungs due to air trapping in the alveoli. This leads to increased anteroposterior diameter of the chest. Choices A, B, and D are incorrect. Peripheral edema is swelling caused by fluid retention in tissues, not associated with a barrel chest in emphysema. Bacterial infections in the lungs can lead to conditions like pneumonia but do not directly cause a barrel chest. Muscle atrophy of the diaphragm could affect breathing mechanics but is not specifically linked to the development of a barrel chest in emphysema.
