Correct Answer: C

Rationale: Nurse Sandra should consider Cindy, 7 years old who has been absent due to skin lesions, as a priority for home visitation. Skin lesions can indicate potential health issues that need to be addressed promptly. Cindy's frequent absences could be a sign that her condition is affecting her school attendance and overall well-being. By conducting a home visit, Nurse Sandra can assess Cindy's living environment, provide appropriate care recommendations, and ensure that she receives necessary medical attention. This proactive approach can help address Cindy's health concerns and support her academic performance.

Correct Answer: A

Rationale: Selective IgA deficiency is a primary immunodeficiency disorder characterized by low or absent levels of immunoglobulin A (IgA) in the blood. Since IgA plays a crucial role in mucosal immunity and defense against pathogens at mucosal surfaces, individuals with this deficiency are more susceptible to recurrent bacterial infections, particularly of the respiratory and gastrointestinal tracts. In contrast, severe combined immunodeficiency (SCID) is a more severe immunodeficiency disorder affecting T and B lymphocytes, chronic granulomatous disease (CGD) is a disorder of phagocytes, and autoimmune hemolytic anemia is an autoimmune disease involving red blood cells, none of which are directly associated with selective IgA deficiency.

Correct Answer: B

Rationale: Radiologic procedures are typically not used as the least screening assessment by nurses in a perinatal unit. The nurse's initial screening assessments usually focus on gathering information through techniques such as physical examination, interviews, and reviewing laboratory results. Radiologic procedures, such as X-rays or CT scans, are usually ordered by physicians once a more specific diagnostic need has been identified, based on the initial screening assessments performed by the nurse. Therefore, in this scenario, the least screening assessment to be used by the nurse would be radiologic procedures.

Correct Answer: A

Rationale: In this case, the patient is experiencing respiratory acidosis as indicated by the low pH (7.28), elevated PaCO2 (65 mmHg), and elevated HCO3- (30 mEq/L). The primary acid-base disturbance is respiratory acidosis due to the retention of carbon dioxide (PaCO2 >45 mmHg) leading to an increase in HCO3- as a compensatory mechanism to maintain pH within normal limits. The elevated HCO3- levels (metabolic compensation) are trying to counterbalance the increased PaCO2 levels (respiratory acidosis) by increasing bicarbonate to attempt to normalize the pH. Overall, the ABG analysis shows respiratory acidosis with metabolic compensation in this COPD patient with an acute exacerbation and severe dyspnea.

Correct Answer: D

Rationale: The desired nursing action to help the pregnant patient make a decision on breastfeeding is to assist in identifying a breastfeeding goal and plan. When patients are indecisive about breastfeeding, it is essential for the nurse to support them in setting specific goals and creating a plan that aligns with their values and circumstances. This approach can help the patient feel empowered and confident in their decision-making process. Providing pamphlets and books (choice A) may be helpful, but personalized assistance in identifying a breastfeeding goal and plan is more likely to address the patient's individual needs and concerns. Providing ample time for the patient to decide (choice B) is important, but guidance and support in setting a clear goal can facilitate the decision-making process. Referring the patient to a nutritionist (choice C) may be beneficial for dietary concerns but may not directly address the decision-making process regarding breastfeeding.
