The nurse is assessing a 64-year-old female patient. The patient states that she is able to reduce the risk of urinary tract infections (UTIs) by drinking a quart of cranberry juice a day. Which health condition, if present in this patient, contraindicates the use of cranberry juice?

Correct Answer: C

Rationale: Cranberry juice has the potential to interact with warfarin, a common blood thinner prescribed for conditions such as atrial fibrillation. Cranberry juice contains components that can inhibit the metabolism of warfarin in the body, leading to an increased risk of bleeding. Therefore, patients taking warfarin should avoid or limit their intake of cranberry juice to prevent potential negative interactions. In this case, the patient's use of warfarin to manage atrial fibrillation contraindicates the consumption of cranberry juice in large quantities. It is essential to consult a healthcare provider before making any changes to the diet, especially when taking medications that may interact with certain foods or beverages.

Correct Answer: A

Rationale: A nurse caring for a patient who presents with a thin vaginal discharge with a strong fishy odor should prepare for performing a whiff test. The whiff test, also known as the amine or sniff test, is used to aid in the diagnosis of bacterial vaginosis (BV). BV is a common vaginal infection characterized by an overgrowth of harmful bacteria in the vagina and can cause symptoms like thin, grayish-white discharge with a strong fishy odor.

Correct Answer: A

Rationale: Urethritis is inflammation of the urethra usually caused by an infection. Neisseria gonorrhoeae, commonly known as gonorrhea, is a sexually transmitted bacterium known to cause urethritis. It is a common cause of urethritis in sexually active individuals. Escherichia coli is associated with urinary tract infections but not typically urethritis. Pregnancy is not a cause of urethritis. Spermicides can potentially irritate the urethra but are not a common cause of urethritis.

Correct Answer: D

Rationale: The statement "I should take the prescribed antibiotics until I feel better" indicates effective teaching after a new diagnosis of nonlactational mastitis. Nonlactational mastitis is commonly treated with antibiotics to help clear up the infection. It is crucial for the patient to follow the prescribed antibiotic regimen as directed by their healthcare provider to ensure the infection is fully treated and to prevent it from worsening or recurring. Compliance with the antibiotic treatment plan is essential for successful management of nonlactational mastitis.

Correct Answer: A

Rationale: A total simple mastectomy is a type of mastectomy that removes the entire breast, including the breast tissue, nipple, and areola, but it leaves the chest wall muscles intact. In this procedure, the lymph nodes under the arm (axillary lymph nodes) are not typically removed. The total simple mastectomy is usually performed when the breast cancer is small and localized, and there is no evidence of spread to the surrounding lymph nodes or chest wall. This surgery is considered less extensive than other types of mastectomies, such as modified radical mastectomy, skin-sparing mastectomy, or nipple-sparing mastectomy, which involve different levels of tissue removal.
