Nurse Nora monitors the patient, knowing that which finding indicates an adequate contraction pattern?

Correct Answer: A

Rationale: An adequate contraction pattern during labor is characterized by regular contractions occurring at a frequency of three to 5 contractions in a 10-minute period, with resultant cervical dilatation. This pattern indicates efficient uterine activity that is helping to progress labor by dilating the cervix. In option A, the contractions are occurring at an appropriate frequency and are resulting in cervical dilatation, making it the correct choice for indicating an adequate contraction pattern.

Correct Answer: B

Rationale: The scenario described in the question is most indicative of endometriosis. Endometriosis is a gynecological condition in which tissue similar to the lining of the uterus grows outside of the uterus. Classic symptoms of endometriosis include cyclic pelvic pain, dysmenorrhea (painful periods), and infertility. The presence of a "chocolate cyst" (also known as an endometrioma) within the ovary on pelvic ultrasound is a characteristic finding in endometriosis. These cysts are filled with old blood, giving them a dark, chocolate-like appearance on imaging. Polycystic ovary syndrome (PCOS) typically presents with irregular periods, signs of hyperandrogenism, and multiple small follicles on ultrasound. Ovarian torsion and ovarian cyst rupture would present with acute-onset symptoms and may not necessarily be associated with cyclic pelvic pain and dysmenorrhea as described in the

Correct Answer: B

Rationale: In a patient with chronic kidney disease presenting with metabolic acidosis, the compensatory mechanism the body is most likely to employ to normalize pH is increased bicarbonate reabsorption in the kidneys. The kidneys play a crucial role in maintaining acid-base balance by regulating bicarbonate levels in the blood. In metabolic acidosis, there is an excess of non-volatile acids in the body, leading to a decrease in blood pH. To compensate for this acidosis, the kidneys increase the reabsorption of filtered bicarbonate ions from the renal tubules back into the blood. This process helps to raise the bicarbonate levels in the blood, which in turn helps to neutralize excess hydrogen ions and restore the blood pH towards normal levels. Hyperventilation (A) is a compensatory mechanism for respiratory acidosis, not metabolic acidosis. Increased renal excretion of hydrogen ions (C) and decreased renal excretion of bicarbonate ions

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: Participating in professional organizations can provide Nurse Bea with numerous opportunities to network with other professionals in the field, stay updated with the latest trends and developments in nursing, access resources for professional growth, and even participate in leadership roles within the organization. Being active in a professional organization can help Nurse Bea build her professional profile, gain recognition, and open up possibilities for career advancement and opportunities for collaboration and learning from peers. It can also help her stay connected with the broader nursing community and enhance her visibility within the field. Engaging with a professional organization is a valuable way for Nurse Bea to enhance her career alongside pursuing further education.

Correct Answer: A

Rationale: The diagnostic examination for osteoporosis typically involves measuring bone density. This is usually done through a dual-energy x-ray absorptiometry (DEXA) scan, which is considered the gold standard for assessing bone density. Osteoporosis is characterized by decreased bone mass and deterioration of bone tissue, leading to increased bone fragility and risk of fractures. Measuring bone density helps in diagnosing osteoporosis by identifying areas of low bone density, assessing the risk of fractures, and monitoring the effectiveness of treatment. Weight, blood volume, and height are not directly used as primary indicators for diagnosing osteoporosis.

Correct Answer: C

Rationale: Providing oral rehydration with electrolyte solutions is the appropriate action for managing a conscious patient with suspected heat cramps. Heat cramps are muscle pains or spasms that often occur during intense exercise in hot environments when a person sweats excessively, losing both fluids and electrolytes. Replenishing lost fluids and electrolytes through oral rehydration helps address the underlying cause of the cramps and provides relief to the patient. Massaging the affected muscles vigorously can potentially worsen the condition, applying cold packs is not usually recommended for heat-related conditions, and encouraging the patient to continue strenuous activity can lead to further complications.

Correct Answer: C

Rationale: Mast cells are primarily responsible for mediating allergic responses such as severe allergies. When an allergen triggers the immune response, mast cells release histamine, leukotrienes, and other inflammatory mediators. These substances cause symptoms such as difficulty breathing, hives, and swelling. Basophils also release histamine, but mast cells are more abundant in tissues and play a significant role in allergic reactions. Eosinophils are involved in allergic reactions but are more focused on combating parasitic infections. Neutrophils are not typically involved in allergic responses but play a key role in combating bacterial infections.

Correct Answer: B

Rationale: A living will is a legal document that allows an individual to express their wishes regarding medical treatment in the event they become unable to make decisions. It specifically outlines the medical treatments a person chooses to refuse or accept under certain circumstances. It is important to differentiate a living will from a durable power of attorney, which designates someone to make healthcare decisions on behalf of the individual when they are unable to do so, and advance directives, which encompass both a living will and a durable power of attorney for healthcare. The living will serves as a guide for healthcare professionals and family members to honor the individual's preferences for medical care.
