Correct Answer: B

Rationale: Running water in the sink or shower is a priority nursing measure to stimulate the sensation of voiding in postpartum mothers experiencing difficulty due to edema and trauma of the perineum. The sound and sight of running water can help relax the pelvic floor muscles and trigger the urge to void. This technique is commonly used in clinical practice to facilitate voiding and prevent urinary retention in postpartum women.

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: B

Rationale: Encouraging the patient to practice controlled coughing techniques would be the most appropriate intervention to address the symptoms of chronic cough and excessive sputum production in a patient with end-stage COPD receiving palliative care. Controlled coughing techniques can help the patient effectively clear respiratory secretions and improve airway clearance without the need for additional medications or interventions. This approach focuses on optimizing the patient's ability to manage their symptoms and maintain comfort, which aligns with the goals of palliative care. Administering bronchodilator medications, prescribing mucolytic medications, or referring the patient to a respiratory therapist for breathing exercises may have limited effectiveness in this advanced stage of the disease, and controlled coughing techniques would be a more practical and patient-centered approach to symptom management.

Correct Answer: B

Rationale: The epigastrium is the upper middle region of the abdomen, lying above the umbilical region and between the hypochondriac regions. It contains several organs including the duodenum, pancreas, portion of the liver, and the pyloric end of the stomach. The duodenum is the first part of the small intestine, the pancreas is a crucial organ for digestion and hormone regulation, the liver aids in digestion and detoxification, and the pyloric end of the stomach connects the stomach to the small intestine for further digestion and absorption of nutrients. These organs are typically assessed and examined when focusing on the epigastrium during a physical examination.

Correct Answer: B

Rationale: In the scenario of a woman in active labor experiencing a prolonged second stage with inadequate expulsive efforts, the appropriate nursing intervention to facilitate fetal descent would be to apply fundal pressure. Fundal pressure, or applying pressure on the upper abdomen just above the uterine fundus, can help in directing the fetal head downwards and aiding in the descent through the birth canal. It is important to note that fundal pressure should be applied carefully and with proper technique to prevent excessive force that could potentially harm the mother or the baby. Encouraging the mother to push forcefully during contractions can be helpful, but the addition of fundal pressure can provide extra assistance in cases of inadequate progress. Immediate cesarean section may be considered if other interventions are unsuccessful or if there are concerns for fetal distress. Administering intravenous magnesium sulfate for uterine relaxation is not indicated in this situation.
