The best time for a woman of childbearing age to perform breast self-examination is
- A. during her menstrual period
- B. 2 days before the onset of her menstrual period
- C. 1 week after her menstrual period ends
- D. the day her menstrual period begins
Correct Answer: C
Rationale: The best time for a woman of childbearing age to perform breast self-examination is 1 week after her menstrual period ends. This is because breast tissue tends to be less tender and lumpy during this time, making it easier to detect any abnormalities. Performing the examination at this time allows for a more accurate assessment of the breasts. Additionally, hormonal changes during the menstrual cycle can affect breast tissue, so performing the examination post-menstruation reduces the likelihood of false alarms. Choices A, B, and D are not ideal times as breast tenderness and hormonal fluctuations during the menstrual period can make it challenging to accurately detect abnormalities.

Superinfections are more common with:
- A. Use of narrow spectrum antibiotics
- B. Short courses of antibiotics
- C. Use of antibiotics that are completely absorbed from the small intestines
- D. Use of antibiotic combinations covering both gram positive and gram negative bacteria
Correct Answer: D
Rationale: The correct answer is D because using antibiotic combinations covering both gram positive and gram negative bacteria can disrupt the balance of normal flora in the body, leading to superinfections. Gram positive and gram negative bacteria have different susceptibility patterns, so using a combination of antibiotics increases the likelihood of killing off a wider range of bacteria, including the beneficial ones. This disruption paves the way for opportunistic pathogens to overgrow and cause superinfections. Choices A, B, and C are incorrect because narrow spectrum antibiotics target specific bacteria, short courses of antibiotics reduce the risk of resistance and overgrowth, and antibiotics completely absorbed from the small intestines have minimal impact on gut flora compared to systemic antibiotics.
A patient who has recently undergone ESWL for the manage her new ileal conduit in the home setting. To treatment of renal calculi has phoned the urology prevent leakage or skin breakdown, the nurse should
- A. Remind the patient that renal calculi have a encourage which of the following practices?
- B. Empty the collection bag when it is between on
- C. half
- D. and two-thirds full.
Correct Answer: B
Rationale: The correct answer is B. Emptying the collection bag when it is between half and two-thirds full helps prevent leakage and skin breakdown by maintaining proper drainage and preventing overfilling. This practice also reduces the risk of urinary stasis and infection.
Choice A is incorrect because it is not related to the management of an ileal conduit. Choice C is incorrect as it does not address the specific issue of proper bag emptying to prevent leakage. Choice D is incorrect as waiting until the bag is too full can lead to increased pressure, potential leakage, and skin breakdown.
Desmopressin reduces urine volume in which of the following condition?
- A. Central (neurogenic) diabetes insipidus
- B. Renal (nephrogenic) diabetes insipidus
- C. Both (a) and (b)
- D. Neither (a) nor (b)
Correct Answer: A
Rationale: Desmopressin reduces urine volume by mimicking the effects of antidiuretic hormone (ADH). In central diabetes insipidus, there is a deficiency of ADH production, so desmopressin can help by supplementing ADH. In renal diabetes insipidus, the kidneys do not respond to ADH, so desmopressin would not be effective. Therefore, the correct answer is A. Choice B is incorrect because desmopressin does not address the underlying issue of kidney insensitivity to ADH. Choice C is incorrect because desmopressin is effective only in central diabetes insipidus. Choice D is incorrect because desmopressin is effective in central diabetes insipidus.
Combivir is a combination therapy used to treat HIV and AIDS include which * of the following drugs?
- A. Lamivudine and stavudine
- B. Lamivudine and zidovudine
- C. Abacavir and zidovudine
- D. Abacavir and stavudine
Correct Answer: B
Rationale: The correct answer is B: Lamivudine and zidovudine. Combivir is a combination therapy that consists of these two drugs. Lamivudine and zidovudine work together to inhibit the replication of the HIV virus. Lamivudine is a nucleoside reverse transcriptase inhibitor, while zidovudine is a nucleoside analog reverse transcriptase inhibitor. Both drugs target different stages of the HIV life cycle, making them effective when used in combination.
Choice A (Lamivudine and stavudine) is incorrect because stavudine is not part of the Combivir combination therapy. Choice C (Abacavir and zidovudine) is incorrect because abacavir is not included in Combivir. Choice D (Abacavir and stavudine) is incorrect because stavudine is not part of the Combivir combination therapy.
During a genital examination, the nurse notices that a male patient has clusters of small vesicles on the
- A. The nurse recognizes that these lesions are:
- B. Peyronie diseas
- C. Genital herpes.
- D. Genital warts.

Rationale: Rationale:
1. Genital herpes presents as clusters of small vesicles on the genitals.
2. The vesicles are typically painful and can ulcerate.
3. The presence of vesicles is a key feature of genital herpes.
4. Peyronie's disease is characterized by penile curvature, not vesicles.
5. Genital warts are caused by HPV and present as cauliflower-like growths, not vesicles.
