When communicating with a patient who is experiencing delirium, what is the nurse's priority?
- A. Use complex language to explain the patient's condition.
- B. Provide clear and simple explanations to minimize confusion.
- C. Ignore the patient's confusion and proceed with the conversation.
- D. Speak loudly to ensure the patient can hear.
Correct Answer: B
Rationale: When communicating with a patient experiencing delirium, the nurse's priority is to provide clear and simple explanations to minimize confusion. Delirium can cause disorientation, confusion, and impaired cognitive function, making it difficult for the patient to understand complex information. Using simple language and clear explanations can help the patient better comprehend the situation and reduce anxiety. It is essential for the nurse to speak calmly, use reassuring gestures, and maintain a supportive presence to effectively communicate with a delirious patient. This approach can help establish a sense of trust and foster a therapeutic nurse-patient relationship during the challenging experience of delirium.

The diagnostic examination for osteoporosis is geared towards measuring
- A. Bone density
- B. Weight
- C. Blood volume
- D. Height
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.
After the successful vaginal1 delivery, medication was ordered to be given immediately. The supervisor reassured the newly hired nurse that everything will be fine because the medication will
- A. promote vasoconstriction of uterine muscles
- B. hasten uterine contractility and control bleeding
- C. facilitate the return of pre pregnancy vital signs
- D. promote vasodilation of uterine muscles
Correct Answer: B
Rationale: The medication given after a successful vaginal delivery that helps to hasten uterine contractility and control bleeding is typically an oxytocic agent, such as oxytocin. Oxytocin helps the uterus to contract effectively, which is important for preventing excessive bleeding after delivery. This medication is commonly used in the postpartum period to help the uterus return to its normal size and position. The supervisor reassured the newly hired nurse that everything will be fine because this medication will help promote uterine contractions and control bleeding, which are crucial steps in the postpartum management.
A patient with a history of sickle cell disease presents with severe abdominal pain, fever, and jaundice. Laboratory tests reveal anemia, reticulocytosis, elevated indirect bilirubin, and presence of Howell-Jolly bodies on peripheral blood smear. Which of the following conditions is most likely to cause these findings?
- A. Acute splenic sequestration crisis
- B. Aplastic crisis
- C. Hemolytic crisis
- D. Vaso-occlusive crisis
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
Which of the following is a common complication associated with long-term use of corticosteroids in orthopedic patients?
- A. Osteoporosis
- B. Hypertension
- C. Hyperkalemia
- D. Hyperthyroidism
Correct Answer: A
Rationale: Osteoporosis is a common complication associated with long-term use of corticosteroids in orthopedic patients. Corticosteroids can lead to bone loss by inhibiting bone formation and promoting bone resorption, resulting in decreased bone mineral density and increased risk of fractures. Therefore, patients on long-term corticosteroid therapy, especially in high doses, should be monitored closely for osteoporosis and receive appropriate preventive measures such as calcium, vitamin D supplementation, and bisphosphonates to mitigate the risk of bone thinning and fractures.
A document that lists the medical treatment a person chooses to refuse if unable to make decisions is the:
- A. Durable power of attorney
- B. Living will
- C. Informed consent
- D. Advance directives
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.
