Correct Answer: D

Rationale: The most appropriate question to ask during the assessment of a newly admitted Person Who Uses Drugs (PWUDs) like Korino is to ask about the amount of drug used, its effects, and how long he has been using. This question provides valuable information for treatment planning and understanding the extent of Korino's drug use. By asking about the specific details of his drug use, the nurse can assess the severity of the addiction, potential health risks, and the duration of substance abuse. This information is crucial for developing an individualized treatment plan and providing appropriate care for Korino's needs. Asking open-ended questions about drug use also helps build rapport and trust between the nurse and the patient, which is essential for effective treatment.

Correct Answer: C

Rationale: Placenta previa is a condition in pregnancy where the placenta implants low in the uterus, partially or completely covering the cervix. This can lead to painless, bright red vaginal bleeding in the third trimester. However, in some cases, placenta previa can also present with sudden onset of severe lower abdominal pain and signs of shock, such as syncope, pallor, and abdominal distention due to concealed bleeding. In severe cases, the bleeding can be significant and life-threatening for both the mother and the baby. It is important to promptly diagnose and manage placenta previa to prevent complications.

Correct Answer: D

Rationale: The patient mentioned in the scenario presents with delayed puberty, short stature, and a childlike appearance. These symptoms are indicative of growth hormone deficiency (GHD). GHD is a condition where the pituitary gland does not produce enough growth hormone, which is crucial for normal growth and development.

Correct Answer: C

Rationale: Assessing the patient for respiratory distress is the important nursing intervention that must be done in this situation. The scenario provided indicates that the patient with chronic obstructive pulmonary disease (COPD) is experiencing increased work of breathing, which puts them at risk for respiratory distress. It is crucial for the nurse to monitor the patient's respiratory status closely, including assessing their oxygen saturations, respiratory rate, and effort, to identify any signs of respiratory distress early and intervene promptly. This proactive assessment can help prevent further deterioration of the patient's condition and ensure appropriate nursing interventions are implemented promptly.

Correct Answer: B

Rationale: The independent variable in an experiment is the variable that is manipulated or determined by the researcher. In this hypothesis, the nurse is suggesting that the age of the patient (elderly vs. younger) influences the aggressiveness of treatment received. Therefore, the age of the patient is the independent variable in this scenario. The dependent variable would be the degree of treatment received, as it is expected to be influenced by the independent variable, which is the age of the patient.
