1. Why is it important for a patient to take a new oral contraceptive at the same time each day?

• A. Taking the medication at the same time each day helps maintain stable hormone levels, which is critical for preventing pregnancy.
• 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 is crucial for maintaining stable hormone levels, which is essential for the contraceptive's effectiveness in preventing pregnancy. Choice B is incorrect because the primary reason for taking the medication consistently is hormone level stability, not specifically to reduce breakthrough bleeding. Choice C is incorrect as it focuses on absorption and effectiveness, which are important but do not address the main reason for consistent timing. Choice D is incorrect because missing doses can impact contraceptive efficacy, making consistent timing essential for optimal protection.

2. In the ICU setting, a client transported from surgery following open heart bypass grafting will likely have his or her core temperature measured by:

• A. oral thermometer.
• B. rectal thermometer.
• C. esophageal thermometer.
• D. temporal artery thermometer.

Correct answer: C

Rationale: An esophageal thermometer is commonly used in ICU settings to accurately measure core body temperature, especially in post-surgical patients. The esophageal thermometer provides a more precise measurement of core temperature compared to other methods like oral, rectal, or temporal artery thermometers. In the ICU, accuracy in temperature measurement is crucial for detecting and responding to changes promptly, making the esophageal thermometer the preferred choice in this scenario.

3. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What therapeutic effect is expected from this medication?

• A. Reduction in prostate size and improvement in urinary symptoms
• B. Increase in urine flow and relief of urinary obstruction
• C. Improvement in erectile function
• D. Relief of pain associated with BPH

Correct answer: A

Rationale: The correct answer is A: Reduction in prostate size and improvement in urinary symptoms. Finasteride works by reducing the size of the prostate gland, which in turn helps alleviate urinary symptoms such as frequency, urgency, weak stream, and incomplete emptying of the bladder. Choice B is incorrect as while finasteride can improve urine flow indirectly by reducing prostate size, it does not directly increase urine flow. Choice C is incorrect because finasteride is not intended to improve erectile function. Choice D is incorrect as finasteride does not primarily provide relief from pain associated with BPH.

4. Which of the following are characteristic, localized cardinal signs of acute inflammation? (Select ONE that does not apply.)

• A. Redness
• B. Fatigue
• C. Swelling
• D. Warmth

Correct answer: B

Rationale: The correct answers are A, C, and D. Redness, swelling, and warmth are classic signs of acute inflammation. Redness occurs due to increased blood flow, swelling is caused by leakage of fluid into tissues, and warmth is due to the vasodilation and increased blood flow in the affected area. Fatigue is not a cardinal sign of acute inflammation and is not directly associated with the inflammatory response.

5. Which of the following eye disorders manifests with red eye, pain, and visual acuity changes?

• A. Bacterial conjunctivitis
• B. Acute closed-angle glaucoma
• C. Chronic open-angle glaucoma
• D. Blepharitis

Correct answer: B

Rationale: Acute closed-angle glaucoma presents with symptoms such as a red eye, severe pain, and rapid visual acuity changes due to increased intraocular pressure. This condition is considered an ophthalmologic emergency. Bacterial conjunctivitis typically presents with redness, discharge, and irritation but is not associated with severe pain or visual changes. Chronic open-angle glaucoma is usually asymptomatic until advanced stages and does not typically present with acute pain. Blepharitis involves inflammation of the eyelid margins and is characterized by redness and irritation, but it does not cause severe pain or acute visual changes.
