Correct Answer: C

Rationale: When encountering patients who are stressed due to their health condition, the best way for a nurse to communicate is through empathizing. Empathy involves understanding and sharing the feelings of another person, which can help the nurse connect with the patient on an emotional level. Empathizing allows the nurse to show genuine care and concern for the patient's well-being, fostering a trusting and supportive relationship. This approach can help alleviate the patient's stress and make them feel understood and supported during a difficult time. Sympathizing and sharing may come across as insincere or minimize the patient's experiences, while listening is important but combining it with empathy enhances the overall communication experience.

Correct Answer: A

Rationale: Prior to a gastric lavage procedure, it is essential for the nurse to ensure the correct size of the nasogastric tube is selected. The appropriate size of the tube will allow for effective removal of the ingested poisonous substance during the procedure. Proper sizing also helps in preventing complications such as injury to the gastrointestinal tract or inadequate removal of the substance. This step is crucial for the safe and successful completion of gastric lavage. Reminding parents to be careful, obtaining informed consent immediately, or accusing them of negligence are not immediate responsibilities of the nurse in this context.

Correct Answer: B

Rationale: The most appropriate nursing intervention to facilitate fetal rotation in a woman experiencing persistent occiput posterior position is to assist the mother into a hands-and-knees position. This position can help encourage the baby to rotate into the optimal occiput anterior position for delivery. By being on her hands and knees, gravity can assist in aiding the rotation of the baby. This position can also help relieve pressure on the mother's back and potentially reduce discomfort during labor. Additionally, hands-and-knees position can help open up the pelvis and create more space for the baby to turn. It is a non-invasive and generally well-tolerated intervention to promote fetal rotation in labor.

Correct Answer: C

Rationale: Methotrexate is a medication commonly used in the treatment of rheumatoid arthritis. It is known to have potential hepatotoxic effects, meaning it can harm the liver. Monitoring liver function tests (such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin levels) is essential to detect any liver damage early on during methotrexate therapy. By closely monitoring liver function tests, healthcare providers can assess the medication's impact on the liver and determine if any dose adjustments or discontinuation of the drug is necessary to prevent further liver damage. Regular monitoring of liver function tests helps ensure the safe and effective use of methotrexate in patients with rheumatoid arthritis.

Correct Answer: D

Rationale: A directional hypothesis predicts the direction of the relationship between variables. In this case, the statement "A significant relationship exists between the caring behaviors of the staff-nurses and degree of satisfaction of ostomized patients" clearly indicates the direction of the expected relationship. This hypothesis suggests that there will be a positive or negative relationship between the caring behaviors of staff nurses and the satisfaction of ostomized patients. The terms "significant relationship" and "degree of satisfaction" indicate that the hypothesis is specific and measurable, making it suitable for testing through research methods.
