Correct Answer: A

Rationale: Menopause is the most important risk factor for osteoporosis because it leads to a decrease in estrogen levels, which plays a crucial role in maintaining bone density. After menopause, women are at a higher risk of developing osteoporosis due to loss of estrogen's protective effects on bone mass. Other risk factors like history of previous fracture, being male, and short stature can also contribute to osteoporosis, but menopause has the strongest association with the development of the condition. It is essential for postmenopausal women to be aware of this risk factor and take preventive measures such as regular exercise, adequate calcium and vitamin D intake, and appropriate medical evaluation and treatment as needed.

Correct Answer: C

Rationale: Using an expired skin preparation solution can compromise the safety and effectiveness of the surgical site cleansing. Expired solutions may have reduced efficacy or could cause adverse reactions due to chemical breakdown over time. Therefore, it is essential for the nurse to discard the expired solution and obtain a new one to ensure proper sanitation and reduce the risk of complications during the surgical procedure. It is important to adhere to proper protocols and guidelines in healthcare settings to maintain patient safety and optimal outcomes.

Correct Answer: A

Rationale: Nicotine, a substance found in cigarettes, is known to have harmful effects on pregnancy. Smoking during pregnancy can lead to numerous complications, one of which is the increased risk of delivering a low birth weight infant. Low birth weight infants are born weighing less than 5.5 pounds (2.5 kilograms) and are at a higher risk of various health issues, developmental delays, and even mortality. Therefore, Nurse Emma advised the patient to quit smoking to reduce the risk of having a low birth weight infant.

Correct Answer: B

Rationale: Normal saline is the preferred solution for wound irrigation because it is isotonic and will not damage healthy tissue or delay wound healing. It helps to remove debris and pathogens from the wound, promoting a clean environment for healing. Sterile water can be used if normal saline is not available, but it may cause cellular damage if used in large volumes. Hydrogen peroxide and Betadine solution are not recommended for wound irrigation as they can be cytotoxic to the tissues and interfere with the wound healing process. It's important for the nurse to use evidence-based practice and follow recommended guidelines to promote optimal wound healing outcomes.

Correct Answer: C

Rationale: Naloxone, also known by the brand name Narcan, is used to reverse the effects of opioid overdose. Opioids can cause respiratory depression, sedation, and other signs of toxicity. Administering naloxone can quickly reverse these effects, restoring the patient's breathing and consciousness. This makes it the appropriate choice for reversing all signs of toxicity related to opioids. Digibind (Digoxin) is used to reverse toxicity from digoxin specifically. Atropine sulfate is used for bradycardia. Diazepam (Valium) is a benzodiazepine used for anxiety, seizures, and muscle relaxation, not for reversing toxicity.
