A nurse is preparing to perform a gastric lavage procedure for a patient with gastrointestinal bleeding. What action should the nurse prioritize to ensure procedural effectiveness?

Correct Answer: D

Rationale: The nurse should prioritize positioning the patient in a left lateral decubitus position during gastric lavage to ensure procedural effectiveness. This position helps to promote optimal drainage of fluid and gastric contents. Placing the patient in a left lateral position allows gravity to assist in the passage of fluid and prevents the risk of aspiration. It also helps to minimize the risk of complications such as reflux of lavage fluid into the respiratory tract. Proper positioning is essential in enhancing the success of the gastric lavage procedure and promoting patient safety.

Correct Answer: A

Rationale: The presentation described is consistent with acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. On examination, the affected eye appears red, with a steamy cornea due to corneal edema and a mid-dilated, non-reactive pupil due to pupillary block from the forward displacement of the iris. Acute angle-closure glaucoma is considered a medical emergency as it can lead to permanent vision loss if not promptly treated. Prompt management involves reducing intraocular pressure to prevent further damage to the optic nerve.

Correct Answer: C

Rationale: Incident reports are a crucial tool for capturing data on adverse events, near misses, and other incidents within a healthcare institution. These reports help in analyzing patterns, identifying areas for improvement, and implementing quality and safety measures. Therefore, incident reports themselves are not something that needs to be prevented; instead, they are a critical part of the risk management process to enhance patient safety and quality of care.

Correct Answer: B

Rationale: Dental caries, commonly known as tooth decay, is characterized by the irreversible demineralization of the enamel and dentin due to acids produced by bacterial activity. This process leads to cavitation and destruction of the tooth structure, ultimately resulting in the formation of a cavity. Gingivitis is inflammation of the gums, periodontitis is inflammation and infection of the supporting structures of the teeth (gums, bone, and ligaments), and a dental abscess is a collection of pus in the tissues surrounding the tooth, none of which are specifically related to the irreversible demineralization of enamel and dentin seen in dental caries.

Correct Answer: C

Rationale: In cases of persistent fetal malpresentation, such as a transverse lie position, a cesarean section is often the safest and most effective intervention to address the abnormal labor presentation. Delivering a baby in a transverse lie position vaginally is associated with high risks, including fetal complications such as umbilical cord prolapse and head entrapment. Therefore, to ensure the safety of both the mother and the baby, a cesarean section is usually the most appropriate and timely intervention to address this situation. It is crucial to prioritize the immediate preparation and facilitation of a cesarean section in cases of persistent fetal malpresentation to prevent potential complications and ensure the best outcome for the mother and the baby.

Correct Answer: D

Rationale: When a patient is crying and continuously pulling at a specific body part, such as Catherine pulling her right ear, it indicates discomfort or pain in that area. Nurse Selma's most appropriate action would be to further assess the description and frequency of the pain. This will help her identify the possible cause of the pain, whether it is due to an ear infection, injury, or any other underlying issue. Understanding the nature and intensity of the pain will guide Nurse Selma in providing appropriate care and intervention for Catherine. It is crucial to address the patient's pain promptly to ensure their comfort and well-being. Referring to the attending physician may be necessary after this initial assessment but assessing the pain should be the immediate priority.

Correct Answer: D

Rationale: A correlational research design is most appropriate when the aim is to find a relationship between two variables. Correlational studies examine how variables are related to each other without manipulating them. This design allows researchers to determine the strength and direction of the relationship between variables, providing valuable insights into the potential associations between different factors. Phenomenological studies focus on understanding individuals' experiences, exploratory studies investigate a topic without predefined hypotheses, and experimental studies involve manipulating variables to observe their effects. Therefore, in the context of aiming to find a relationship between two variables, a correlational research design is the most suitable choice.

Correct Answer: A

Rationale: The primary responsibility for obtaining informed consent lies with the surgeon who will be performing the procedure. Informed consent is a process where the healthcare provider explains the procedure, benefits, risks, and alternatives to the patient, allowing them to make an informed decision about their care. While other healthcare team members may also participate in this process, the ultimate responsibility typically rests with the surgeon as they are the one performing the surgery.

Correct Answer: A

Rationale: Acute splenic sequestration crisis is a complication seen in patients with sickle cell disease characterized by the sudden pooling of sickled red blood cells in the spleen, leading to splenic enlargement, severe anemia, and hypovolemic shock. This pooling results in a rapid drop in hemoglobin levels, causing anemia. The spleen's sequestration of large numbers of red blood cells can cause a sudden rise in the number of immature red blood cells (reticulocytes) in the blood (reticulocytosis). The destruction of these trapped red blood cells in the spleen leads to hemolysis, evidenced by elevated indirect bilirubin levels and the presence of Howell-Jolly bodies (nuclear remnants of erythrocytes) on peripheral blood smear. Patients may present with severe abdominal pain, fever, jaundice, and signs of hemodynamic instability, which
