Pathophysiology Final Exam
1. Prior to administering iodoquinol (Yodoxin), what assessment should the nurse make?
- A. Assess for allergy to iodine.
- B. Note the time the patient last ate.
- C. Assess for skin eruptions.
- D. Assess for ophthalmic symptoms.
Correct answer: A
Rationale: Before administering iodoquinol (Yodoxin), the nurse should assess for allergy to iodine since iodoquinol is a medication containing iodine. Assessing for skin eruptions (choice C) and ophthalmic symptoms (choice D) are not specifically related to iodoquinol administration. Noting the time the patient last ate (choice B) may be relevant for certain medications but is not directly related to assessing for an allergy to iodine in this case.
2. How will taking an oral contraceptive affect the physiologically of an insulin-dependent diabetic patient?
- A. Increase risk of hypoglycemia
- B. Increase heart rate
- C. Increase blood glucose
- D. Increase risk of metabolic alkalosis
Correct answer: C
Rationale: Taking an oral contraceptive can lead to an increase in blood glucose levels in insulin-dependent diabetic patients. This occurs due to the hormonal changes induced by the contraceptive, which can impact insulin sensitivity. Therefore, diabetic patients need to closely monitor their blood glucose levels when starting an oral contraceptive to prevent complications. The other choices are incorrect as oral contraceptives do not typically lead to an increase in heart rate, risk of hypoglycemia, or risk of metabolic alkalosis in this context.
3. What occurs in a client with polycythemia?
- A. Deficient plasma in the blood
- B. Increased lymphatic fluid being produced
- C. Increased red blood cells being produced
- D. Deficient number of red blood cells
Correct answer: C
Rationale: The correct answer is C: Increased red blood cells being produced. Polycythemia is a condition characterized by an elevated number of red blood cells in the blood. This increased concentration of red blood cells can lead to blood thickening and potentially result in complications such as blood clots. Choices A, B, and D are incorrect because polycythemia does not involve deficient plasma, increased lymphatic fluid production, or a deficient number of red blood cells.
4. When starting on oral contraceptives, what key point should the nurse emphasize about taking the medication consistently?
- A. Oral contraceptives should be taken at the same time each day to maintain stable hormone levels and prevent pregnancy.
- B. Oral contraceptives can be taken at any time of day, as long as the schedule is consistent.
- C. Oral contraceptives should be taken in the morning to avoid nighttime side effects.
- D. Oral contraceptives are effective immediately upon starting, regardless of timing.
Correct answer: A
Rationale: When starting on oral contraceptives, it is crucial to take them at the same time each day to maintain stable hormone levels and ensure their effectiveness in preventing pregnancy. Choice B is incorrect because consistency in timing is essential to maximize contraceptive efficacy. Choice C is incorrect as there is no evidence that taking oral contraceptives in the morning helps avoid nighttime side effects. Choice D is incorrect because oral contraceptives do not provide immediate effectiveness and require consistent use to prevent pregnancy.
5. What is the primary cause of primary hypercholesteremia?
- A. High-density lipoprotein (HDL) defects
- B. Monogenic mutations, sedentary lifestyle, and high cholesterol diet
- C. Polygenic mutations and environmental factors
- D. Low-density lipoprotein (LDL) receptor mutation with defects in breakdown
Correct answer: D
Rationale: The correct answer is 'Low-density lipoprotein (LDL) receptor mutation with defects in breakdown.' Primary hypercholesteremia is mainly caused by mutations in the LDL receptor, leading to impaired clearance of LDL cholesterol from the blood. This results in high levels of LDL cholesterol in the bloodstream. Choices A, B, and C are incorrect because they do not directly relate to the primary cause of primary hypercholesteremia.
