Correct Answer: A

Rationale: During an acute asthma attack, one of the expected assessments by the nurse would be diffuse expiratory wheezing. This occurs due to narrowed airways and increased airflow velocity. Choice B, a loose productive cough, is not typically associated with an asthma attack. Choice C, no relief from inhaler, may indicate ineffective treatment but is not a direct assessment finding related to the physical examination. Choice D, fever and chills, are not typical symptoms of an asthma attack and would not be expected findings during the initial assessment of an acute asthma attack.

Correct Answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

Correct Answer: B

Rationale: Late decelerations are concerning as they indicate uteroplacental insufficiency, potentially resulting in fetal hypoxia. Immediate intervention is necessary to address the underlying cause and ensure fetal well-being. Early decelerations are typically benign and associated with head compression during contractions. Accelerations are reassuring and indicate fetal well-being. Moderate variability is a normal finding and indicates a healthy autonomic nervous system response. Therefore, late decelerations (Choice B) require immediate attention, while the other patterns are generally considered normal or benign during labor.

Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is to withhold the blood transfusion. The principle of autonomy ensures that a competent client has the right to refuse treatment, even if their decision conflicts with the wishes of their partner or family. Asking the client to consider a direct donation (Choice A) is not appropriate as it disregards the client's autonomy and religious beliefs. Requesting a consultation with the ethics committee (Choice C) may be considered in complex ethical dilemmas, but in this case, the client's autonomy should be respected first. Asking the client's family to intervene (Choice D) is not appropriate as the client has the right to make their own healthcare decisions based on their religious beliefs.

Correct Answer: A

Rationale: The correct answer is to establish consistent boundaries for the toddler. This approach helps toddlers understand expectations and promotes consistent behavior. Placing the toddler alone or using food rewards may not effectively teach discipline and could be inappropriate. Informing the toddler about feelings when misbehaving may not be developmentally appropriate for a toddler to understand the consequences of their actions.
