foundation of nursing questions

Correct Answer: C

Rationale: The correct answer is C: bacterial endocarditis. Mitral valve stenosis increases the risk of bacterial endocarditis due to turbulent blood flow and potential damage to the heart valve. Prophylactic antibiotics are recommended before certain procedures to prevent bacterial endocarditis in patients with underlying cardiac conditions. Choice A, hypertension, is incorrect as mitral valve stenosis does not directly increase the risk of developing hypertension. Choice B, postpartum infection, is not directly related to the risk associated with mitral valve stenosis. Choice D, upper respiratory infections, is not a specific risk associated with mitral valve stenosis in pregnant patients.

Correct Answer: A

Rationale: The correct answer is A: Rinsing the ears with normal saline after swimming. This is because rinsing with normal saline helps to remove excess moisture and debris, preventing bacterial growth that can lead to otitis externa. Avoiding loud noises (B) is important for overall ear health but does not specifically prevent otitis externa. Instilling antibiotic ointments regularly (C) is not recommended as it can disrupt the ear's natural flora. Avoiding cotton swabs (D) is important to prevent injury but does not directly prevent otitis externa.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): The nurse can presume the patient has candidiasis since miconazole is commonly used to treat fungal infections like vaginal yeast infections caused by Candida. This medication works by stopping the growth of the fungus. Therefore, the patient's use of miconazole indicates a probable diagnosis of candidiasis. Summary of Incorrect Choices: A (Bacterial vaginosis): Miconazole is not used to treat bacterial infections like bacterial vaginosis, which is caused by an imbalance of bacteria in the vagina. B (HPV): Miconazole is not used to treat viral infections like HPV, which is a sexually transmitted infection caused by certain types of human papillomavirus. D (TSS): Miconazole is not used to treat toxic shock syndrome, which is a severe complication of certain bacterial infections and is not typically associated with miconazole use.

Correct Answer: A

Rationale: The correct answer is A: Rate of growth. Malignant cancer cells grow and divide rapidly compared to benign cells. Benign cells are usually slow-growing and have a well-defined border, while malignant cells grow uncontrollably and invade surrounding tissues. The other choices are incorrect because: B: Ability to cause death - Both benign and malignant cells have the potential to cause harm, but the key difference lies in their growth rate and invasiveness. C: Size of cells - The size of cells does not necessarily differentiate between benign and malignant cells. D: Cell contents - While malignant cells may have abnormal cell contents, this is not a defining characteristic when differentiating between benign and malignant cells. E: Ability to spread - While the ability to spread is a key characteristic of malignant cells, the primary differentiating factor in this question is the rate of growth.

Correct Answer: A

Rationale: The correct answer is A: Providing thorough oral care before and after meals. This addresses the risk for impaired skin integrity related to Candidiasis in patients with stage 3 HIV by preventing oral Candidiasis, a common fungal infection. Poor oral hygiene can lead to Candidiasis, which can spread to the skin. Thorough oral care reduces the risk of oral Candidiasis, thereby preventing skin integrity issues. Administering prophylactic antibiotics (B) is not indicated for preventing Candidiasis. Promoting nutrition and fluid intake (C) is important for overall health but does not directly address the risk of impaired skin integrity. Applying skin emollients (D) may help with skin dryness but does not directly address the underlying cause of Candidiasis.
