Pathophysiology Final Exam
1. What nursing diagnosis is suggested by the patient's statement regarding taking extra griseofulvin when she thinks her infection is getting worse?
- A. Deficient knowledge related to correct use of griseofulvin
- B. Effective therapeutic regimen management related to symptom identification
- C. Disturbed thought processes related to appropriate use of griseofulvin
- D. Ineffective coping related to self-medication
Correct answer: C
Rationale: The correct answer is C: 'Disturbed thought processes related to appropriate use of griseofulvin.' The patient's statement shows a misunderstanding of the correct use of griseofulvin by taking extra medication when she believes her infection is worsening. This behavior indicates a disturbance in her thought process regarding the appropriate use of the medication. Choice A is incorrect because the issue is not lack of knowledge but rather a misunderstanding leading to inappropriate actions. Choice B is incorrect as the patient's actions do not demonstrate effective management of her therapeutic regimen. Choice D is incorrect as the patient is not engaged in self-medication but rather misinterpreting signals and self-adjusting the prescribed medication.
2. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What critical information should the nurse provide during patient education?
- A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
- B. Tamoxifen may decrease the risk of osteoporosis, so adequate calcium intake is important.
- C. Tamoxifen may cause weight gain, so patients should monitor their diet.
- D. Tamoxifen may increase the risk of breast cancer, so regular mammograms are essential.
Correct answer: A
Rationale: When a patient is prescribed tamoxifen, a critical piece of information that the nurse should provide during patient education is that tamoxifen may increase the risk of venous thromboembolism. Therefore, patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur. Choice B is incorrect because tamoxifen does not decrease the risk of osteoporosis. Choice C is incorrect as weight gain is a possible side effect of tamoxifen, but it is not a critical piece of information compared to the risk of venous thromboembolism. Choice D is incorrect because tamoxifen is actually used to treat breast cancer, not increase its risk.
3. When a client has their 'fight or flight' system activated, which below is a manifestation of that?
- A. Decreased blood pressure
- B. Decreased heart rate
- C. Decreased respiration rate
- D. Increased glucose levels
Correct answer: D
Rationale: The correct answer is D, 'Increased glucose levels.' When the 'fight or flight' system is activated, the body releases glucose to provide energy for the impending response. This increase in glucose levels helps fuel the body's reaction to the perceived threat or stressor. Choices A, B, and C are incorrect because during the 'fight or flight' response, blood pressure, heart rate, and respiration rate typically increase to prepare the body to confront or flee from the perceived danger.
4. A 30-year-old woman is taking an oral contraceptive and is concerned about the potential side effects. What should the nurse include in the patient education?
- A. Oral contraceptives can cause weight loss and increased energy levels.
- B. Oral contraceptives can cause increased appetite and weight gain.
- C. Oral contraceptives can cause headaches and breast tenderness.
- D. Oral contraceptives have no side effects.
Correct answer: C
Rationale: The correct answer is C: 'Oral contraceptives can cause headaches and breast tenderness.' It is essential for the nurse to educate the patient about common side effects of oral contraceptives, such as headaches and breast tenderness. Choices A, B, and D are incorrect. Weight loss and increased energy levels (Choice A) are not common side effects of oral contraceptives. Similarly, increased appetite and weight gain (Choice B) are not typical side effects. Finally, stating that oral contraceptives have no side effects (Choice D) is inaccurate as they can have various side effects, albeit usually mild and manageable.
5. The neurotransmitter GABA mainly functions to trigger inhibitory postsynaptic potentials (IPSPs). Therefore, when explaining this to a group of nursing students, the nurse will state:
- A. It takes at least three chemical substances (amino acids, neuropeptides, and monoamines) to stimulate any activity between the cells.
- B. There is a symbiotic relationship; therefore, the end result will be depolarization of the postsynaptic membrane.
- C. The combination of GABA with a receptor site is inhibitory since it causes the local nerve membrane to become hyperpolarized and less excitable.
- D. The neurotransmitters will interact with cholinergic receptors to bind to acetylcholine in order to produce hypopolarization within the cell.
Correct answer: C
Rationale: When GABA binds with a receptor site, it causes hyperpolarization of the local nerve membrane, making it less excitable. This hyperpolarization leads to inhibition of nerve cell activity. Choice A is incorrect because GABA is a neurotransmitter itself and does not require three chemical substances to stimulate activity between cells. Choice B is incorrect as GABA triggers inhibitory postsynaptic potentials (IPSPs), leading to hyperpolarization, not depolarization, of the postsynaptic membrane. Choice D is also incorrect as it describes a process involving cholinergic receptors and acetylcholine, which is unrelated to GABA's mechanism of action.
