Correct Answer: B

Rationale: The correct answer is B because Rh incompatibility occurs when an Rh-negative mother carries an Rh-positive fetus. If fetal blood enters the mother's circulation during pregnancy or childbirth, the mother's immune system can produce antibodies against Rh-positive red blood cells, leading to potential harm to future pregnancies. Choices A, C, and D are incorrect because Rh incompatibility does not occur when the fetus is Rh-negative, the father is Rh-positive, or both the father and fetus are Rh-negative.

Correct Answer: A

Rationale: The correct answer is A: A minimum data set. In a long-term care setting funded by Medicare and Medicaid, completing standardized protocols for assessment and care planning for reimbursement involves using a minimum data set, which is a standardized instrument for assessing residents' health status. This set of data elements is necessary for comprehensive assessment and care planning to ensure appropriate reimbursement. The other choices (B, C, D) do not specifically address the standardized protocols required for reimbursement in this setting. An admission assessment and acuity level would be part of the process, but not the primary task being completed in this scenario. A focused assessment on a specific body system or an intake assessment form and auditing phase are not synonymous with the standardized protocols needed for reimbursement in a Medicare/Medicaid-funded long-term care facility.

Correct Answer: A

Rationale: The correct answer is A because sildenafil works by enhancing the effects of nitric oxide, which is released during sexual stimulation to relax the muscles in the penis and increase blood flow for an erection. Therefore, sexual stimulation is necessary for the medication to be effective. Explanation of other choices: B: While sildenafil is typically taken 30 minutes to 4 hours before sexual activity, it does not need to be exactly 1 hour prior. C: Facial flushing and headache are common side effects of sildenafil but do not require immediate reporting unless severe or persistent. D: Sildenafil may cause temporary visual disturbances like changes in color vision, but permanent visual changes are rare.

Correct Answer: B

Rationale: The correct answer is B: There is an increased incidence of disease. Low-income immigrants often face barriers to healthcare access, leading to higher rates of undiagnosed and untreated health conditions. This information is crucial for the nurse to plan appropriate care interventions. Incorrect choices: A: Decreased frequency of morbidity is not accurate as low-income immigrants may experience higher rates of illness due to lack of resources. C: Increased level of health is unlikely in this population due to socioeconomic factors affecting health outcomes. D: Decreased mortality rate is not supported as low-income immigrants may have higher mortality rates due to limited access to healthcare.

Correct Answer: B

Rationale: The correct answer is B: Contraction of bronchial smooth muscle. Histamine release can lead to bronchoconstriction, which narrows the airways and causes difficulty in breathing. This is a common symptom in allergic reactions like asthma. Constriction of small venules (Choice A) is not a typical consequence of histamine release. Dilation of large blood vessels (Choice C) is more associated with histamine's role in increasing vascular permeability. Decreased secretions from gastric and mucosal cells (Choice D) is not directly related to histamine's effects on smooth muscle contraction.
