Which of the following conditions is characterized by chronic hypoxemia, pulmonary hypertension, and right heart failure?
- A. Chronic obstructive pulmonary disease (COPD)
- B. Idiopathic pulmonary fibrosis (IPF)
- C. Pulmonary embolism (PE)
- D. Cor pulmonale
Correct Answer: D
Rationale: Cor pulmonale is a condition characterized by right heart failure secondary to pulmonary hypertension, which is often caused by chronic hypoxemia. Chronic hypoxemia occurs in conditions such as chronic obstructive pulmonary disease (COPD) where there is limited airflow in and out of the lungs, leading to low oxygen levels in the blood. However, the specific characteristic of pulmonary hypertension leading to right heart failure distinguishes cor pulmonale from COPD. Other conditions like idiopathic pulmonary fibrosis (IPF) and pulmonary embolism (PE) may also lead to hypoxemia but are not primarily associated with pulmonary hypertension and right heart failure as in cor pulmonale.

Which of the following is the most common risk factor for the development of ovarian cancer?
- A. Nulliparity
- B. Early menarche
- C. Late menopause
- D. Family history of breast cancer
Correct Answer: A
Rationale: Nulliparity, which refers to never having given birth to a child, is the most common risk factor for the development of ovarian cancer. Women who have never been pregnant have a higher risk of developing ovarian cancer compared to those who have had children. This association is believed to be related to the uninterrupted ovulation cycles that nulliparous women experience, leading to changes in the surface epithelium of the ovary that predispose them to cancer development. Conversely, factors like early menarche, late menopause, and a family history of breast cancer are also associated with an increased risk of ovarian cancer but are not as commonly observed as nulliparity in the general population.
Which of the following dental conditions is characterized by inflammation and infection of the soft tissues surrounding the apex of a tooth root?
- A. Gingivitis
- B. Periodontitis
- C. Dental abscess
- D. Oral candidiasis
Correct Answer: C
Rationale: A dental abscess is a condition characterized by inflammation and infection of the soft tissues surrounding the apex of a tooth root. This infection can result from untreated dental decay, trauma to the tooth, or periodontal disease. The abscess can cause pain, swelling, redness, and even pus formation. Treatment typically involves draining the abscess, removing the source of infection, and possibly prescribing antibiotics to address the infection. If left untreated, a dental abscess can lead to serious complications and spread to other parts of the body.
A patient expresses religious beliefs that conflict with a recommended treatment plan. What is the nurse's best approach?
- A. Disregard the patient's religious beliefs and insist on the recommended treatment.
- B. Listen actively to the patient's religious beliefs, respect their autonomy, and explore alternative options.
- C. Ignore the patient's religious beliefs and proceed with implementing the recommended treatment.
- D. Tell the patient that their religious beliefs are irrelevant to their medical care.
Correct Answer: B
Rationale: The best approach for the nurse in this situation is to listen actively to the patient's religious beliefs, respect their autonomy, and explore alternative treatment options. It is important for the nurse to understand and acknowledge the patient's perspective, even if it conflicts with the recommended treatment plan. By showing respect for the patient's beliefs and involving them in the decision-making process, the nurse can work collaboratively with the patient to find a solution that aligns with their religious beliefs while also addressing their medical needs. This approach promotes patient-centered care and helps build a trusting and therapeutic relationship between the nurse and the patient.
A woman in active labor is diagnosed with an amniotic fluid embolism. What is the priority nursing intervention?
- A. Administering oxygen via face mask
- B. Preparing for immediate cesarean section
- C. Initiating cardiopulmonary resuscitation (CPR)
- D. Inserting an indwelling urinary catheter
Correct Answer: C
Rationale: An amniotic fluid embolism is a rare and life-threatening complication during labor and delivery. It occurs when amniotic fluid or fetal cells enter the maternal circulation, triggering a rapid immune response that can lead to cardiovascular collapse and respiratory failure. The priority nursing intervention for a woman in active labor diagnosed with an amniotic fluid embolism is to initiate cardiopulmonary resuscitation (CPR) to support her vital functions and circulation. Providing immediate CPR can help sustain her until further medical interventions can be implemented. Administering oxygen and preparing for a cesarean section may be necessary but should occur after CPR is initiated to stabilize the woman's condition. Inserting an indwelling urinary catheter is not the priority in this emergency situation, as maintaining adequate cardiac and respiratory function takes precedence.
During CPR, which of the following actions should be performed immediately after activating the emergency response system?
- A. Start chest compressions.
- B. Check for breathing.
- C. Perform abdominal thrusts.
- D. Assess pulse.
Correct Answer: A
Rationale: After activating the emergency response system, the immediate priority in CPR is to begin chest compressions to support blood circulation. High-quality chest compressions are crucial in providing oxygen to vital organs, especially the brain, during cardiac arrest. Starting chest compressions promptly can improve the chances of survival for the person in need of CPR. Checking for breathing, performing abdominal thrusts, or assessing pulse should only be done after initiating chest compressions in the CPR sequence.
