A patient presents with chest pain that occurs at rest and is relieved by nitroglycerin. An electrocardiogram (ECG) may show transient ST-segment elevation. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Unstable angina
- C. Acute myocardial infarction
- D. Prinzmetal's angina
Correct Answer: D
Rationale: Prinzmetal's angina, also known as variant angina, is characterized by episodes of chest pain that occur at rest and are relieved by nitroglycerin. Patients with Prinzmetal's angina may also have transient ST-segment elevation on an electrocardiogram (ECG) during episodes of chest pain. This is due to coronary artery vasospasm, which causes temporary obstruction of blood flow to the heart muscle. Stable angina typically presents with chest pain on exertion that resolves with rest, while unstable angina and acute myocardial infarction present with chest pain that is not relieved with nitroglycerin and are associated with more severe coronary artery disease.

Which of the following signs is indicative of shock in a trauma patient?
- A. Increased heart rate
- B. Hypertension
- C. Rapid capillary refill
- D. Hyperthermia
Correct Answer: C
Rationale: Rapid capillary refill is a sign indicative of shock in a trauma patient. Shock is a life-threatening condition where the body's organs and tissues do not receive adequate blood flow and oxygen, leading to cellular damage and eventual organ failure. In a trauma patient, rapid capillary refill suggests poor perfusion, which is a common feature of shock. The capillary refill time is an important clinical assessment that measures the time it takes for color to return to the nail bed after pressure is applied. In cases of shock, the refill time is faster than normal, indicating a systemic circulatory disturbance. Other signs of shock may include tachycardia (increased heart rate), hypotension (not hypertension), and hypothermia (not hyperthermia).
Human chorionic gonadotropin (HCG), the biologic marker on which pregnancy tests are based, can be detected in the BLOOD as early as which nber of DAYS after the last menstrual period?
- A. 15
- B. 10
- C. 20
- D. 5
Correct Answer: B
Rationale: Human chorionic gonadotropin (HCG) can be detected in the blood as early as 10 days after the last menstrual period. This hormone is produced by the placenta shortly after the embryo attaches to the uterine lining. Pregnancy tests detect HCG levels to determine pregnancy status, and the hormone can be detected earlier in the blood compared to urine tests. Detecting HCG in the blood at around 10 days post ovulation is often the earliest point when a blood test can confirm pregnancy.
A 28-year-old woman presents with lower abdominal pain, dyspareunia, and dysmenorrhea that worsens during menstruation. On pelvic examination, tender nodules are palpated along the uterosacral ligaments. Which condition is most likely to be responsible for these findings?
- A. Polycystic ovary syndrome (PCOS)
- B. Endometriosis
- C. Pelvic inflammatory disease (PID)
- D. Uterine fibroids
Correct Answer: B
Rationale: The clinical presentation of lower abdominal pain, dyspareunia (pain during sexual intercourse), dysmenorrhea (painful periods), and tender nodules along the uterosacral ligaments is highly suggestive of endometriosis. Endometriosis is a condition where the tissue that lines the uterus (endometrium) grows outside the uterus, commonly on the pelvic organs such as the ovaries, fallopian tubes, and the peritoneum. The characteristic tender nodules along the uterosacral ligaments are known as "nodularity" and are a classic finding in endometriosis.
A patient with a history of chronic obstructive pulmonary disease (COPD) is prescribed prednisone for an acute exacerbation. Which instruction is important for the nurse to include in patient education about prednisone therapy?
- A. "Take prednisone with antacids to minimize gastrointestinal upset."
- B. "Avoid abruptly stopping prednisone therapy."
- C. "Increase your intake of potassium-rich foods while taking prednisone."
- D. "Prednisone may cause weight loss, so monitor your weight regularly."
Correct Answer: B
Rationale: It is crucial for patients with COPD who are prescribed prednisone to be educated about the importance of not abruptly stopping the medication. Prednisone is a type of corticosteroid that should be tapered off gradually under the guidance of a healthcare provider to prevent potential withdrawal symptoms and adrenal insufficiency. Suddenly stopping prednisone can lead to serious adverse effects, including fatigue, weakness, joint pain, fever, dizziness, and potentially life-threatening complications. Therefore, adherence to the prescribed tapering schedule is essential to ensure the safe and effective management of COPD exacerbations with prednisone therapy.
Given her problems of hyper vigilance and worry that something terrible will happen to her child, nursing interventions should be aimed at addressing her needs for _______.
- A. Love and belongingness
- B. psychological security
- C. biological integrity
- D. self-esteem
Correct Answer: B
Rationale: Nursing interventions should be aimed at addressing the mother's needs for psychological security. Hyper vigilance and excessive worry about her child's safety indicate a lack of security in her mind. By providing support, reassurance, and education, nurses can help the mother feel more secure in her role as a parent and reduce her feelings of anxiety and distress. Establishing trust and building a therapeutic relationship can also contribute to enhancing the mother's psychological security and well-being.
