1. Which of the following is a characteristic of disseminated intravascular coagulation (DIC)?

• A. Simultaneous stroke and heart attack
• B. Simultaneous clotting and bleeding
• C. Simultaneous clotting and insulin release
• D. Simultaneous bleeding and vomiting

Correct answer: B

Rationale: Disseminated intravascular coagulation (DIC) is characterized by simultaneous clotting and bleeding throughout the body. This imbalance in the body's clotting system leads to the formation of blood clots in small blood vessels, which can consume clotting factors and platelets, ultimately leading to excessive bleeding. Choices A, C, and D are incorrect because they do not describe the characteristic feature of DIC, which involves both clotting and bleeding.

2. A patient is starting on oral contraceptives. What should the nurse emphasize about the importance of taking the medication at the same time each day?

• A. Taking the medication at the same time each day helps maintain stable hormone levels and ensures effectiveness.
• B. Taking the medication at the same time each day reduces the risk of breakthrough bleeding.
• C. Taking the medication at the same time each day ensures consistent absorption and effectiveness.
• D. Taking the medication at the same time each day is important, but missing a dose occasionally is not a concern.

Correct answer: A

Rationale: The correct answer is A. Taking oral contraceptives at the same time each day helps maintain stable hormone levels and ensures their effectiveness in preventing pregnancy. Choice B is incorrect because the primary emphasis of consistent timing is on hormone levels and effectiveness, not on reducing breakthrough bleeding. Choice C is incorrect because while consistent absorption is a factor, the main focus is on maintaining stable hormone levels. Choice D is incorrect as missing doses can significantly impact contraceptive efficacy.

3. Hematopoiesis occurs primarily in the bone marrow. What cells are formed during this process?

• A. Pancreatic beta cells
• B. Red blood cells
• C. Gastric parietal cells
• D. Neurons and glial cells

Correct answer: B

Rationale: The correct answer is B: Red blood cells. Hematopoiesis is the process of blood cell formation that primarily occurs in the bone marrow. Red blood cells are one of the main cell types formed during this process. Pancreatic beta cells (Choice A), gastric parietal cells (Choice C), and neurons and glial cells (Choice D) are not formed during hematopoiesis. Pancreatic beta cells are involved in insulin production, gastric parietal cells secrete gastric acid, and neurons and glial cells are part of the nervous system.

4. The unique clinical presentation of a 3-month-old infant in the emergency department leads the care team to suspect botulism. Which assessment question posed to the parents is likely to be most useful in the differential diagnosis?

• A. Has your child received all recommended vaccinations?
• B. Has your child been feeding poorly or showing signs of constipation?
• C. Has your child been exposed to any sick individuals?
• D. Has your child been displaying signs of respiratory distress?

Correct answer: B

Rationale: The correct answer is B. Poor feeding and constipation are common early symptoms of infant botulism, which is caused by a neurotoxin that impairs muscle function. Option A is unrelated to the presentation of botulism. Option C does not directly relate to the symptoms of botulism. Option D is more indicative of respiratory issues rather than the constellation of symptoms seen in botulism.

5. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What should the nurse include in the patient education?

• A. The medication is expected to reduce the size of the prostate, which should improve urinary symptoms over time.
• B. The medication will improve symptoms within a few days.
• C. The medication will cure BPH after treatment is complete.
• D. The medication may cause erectile dysfunction as a side effect.

Correct answer: A

Rationale: Finasteride is expected to reduce the size of the prostate, which should improve urinary symptoms over time, although the effects may take several weeks or months to become noticeable.
