What is a function of the male reproductive system?
- A. To manufacture testosterone
- B. To manufacture progesterone
- C. To manufacture ova
- D. To manufacture estrogen
Correct Answer: A
Rationale: The correct answer is A because the male reproductive system's primary function is to produce testosterone, a hormone responsible for male characteristics and sperm production. Testosterone is produced in the testes by Leydig cells. Choices B, C, and D are incorrect because progesterone is produced by the female ovaries, ova are produced by the female reproductive system, and estrogen is the primary female sex hormone.

You are called to a scene for a 48-year-old male presenting with sudden onset of severe shortness of breath, tachypnea, and a rapid pulse. He is alert and oriented, and physical exam reveals a swollen right calf with tenderness. Which condition is most likely causing his symptoms?
- A. Acute myocardial infarction
- B. Pulmonary embolism
- C. Tension pneumothorax
- D. Severe asthma attack
Correct Answer: B
Rationale: The correct answer is B: Pulmonary embolism. In this case, the patient has sudden onset of severe shortness of breath, tachypnea, a rapid pulse, and a swollen right calf with tenderness, which are classic signs of a pulmonary embolism. A pulmonary embolism occurs when a blood clot travels to the lungs, blocking blood flow and causing respiratory distress. The presentation of symptoms in this patient aligns with a pulmonary embolism rather than the other choices. Acute myocardial infarction typically presents with chest pain, not primarily shortness of breath. Tension pneumothorax presents with asymmetrical chest rise, tracheal deviation, and absent breath sounds. Severe asthma attack typically presents with wheezing and prolonged expiratory phase.
A 22-year-old man is brought to the hospital after crashing his motorcycle into a telephone pole. He is unconscious and in profound shock. He has no open wounds or obvious fractures. The cause of his shock is MOST LIKELY caused by:
- A. A subdural hematoma
- B. An epidural hematoma
- C. A transected lumbar spinal cord
- D. Hemorrhage into the chest or abdomen
Correct Answer: D
Rationale: The correct answer is D: Hemorrhage into the chest or abdomen. In this scenario, the man has no open wounds or obvious fractures, ruling out subdural and epidural hematomas. A transected spinal cord would result in neurological deficits rather than shock. Hemorrhage into the chest or abdomen can lead to significant blood loss causing shock, especially in trauma patients. This is supported by the mechanism of injury (motorcycle crash) and the absence of external bleeding.
The nurse is caring for a patient who is scheduled to undergo a surgical procedure. The nurse is completing an assessment and reviews the patient's laboratory tests and allergies and prepares the patient for surgery. In which perioperative nursing phase is the nurse working?
- A. Perioperative
- B. Preoperative
- C. Intraoperative
- D. Postoperative
Correct Answer: B
Rationale: The correct answer is B: Preoperative. In the preoperative phase, the nurse assesses the patient, reviews relevant information (such as lab tests and allergies), and prepares the patient for surgery. This phase occurs before the surgical procedure takes place.
A: Perioperative includes preoperative, intraoperative, and postoperative phases.
C: Intraoperative refers to the phase during the actual surgical procedure.
D: Postoperative occurs after the surgery is completed.
Therefore, the nurse is working in the preoperative phase as she is preparing the patient before the surgery.
One way to prevent burns and scalds is to
- A. Place hot drinks on the edges of tables so that they will be easier to reach
- B. Serve residents drinks while they are standing
- C. Leave warm water applications on for 30 minutes at a time
- D. Check water temperature before giving a bath or shower
Correct Answer: D
Rationale: Step 1: Checking water temperature before giving a bath or shower ensures it is not too hot, preventing burns.
Step 2: This practice aligns with safety guidelines to prevent scalds and burns.
Step 3: It demonstrates a proactive approach to protecting individuals from harm.
Step 4: Other choices are incorrect as they involve risky behaviors that can lead to burns or scalds.
Summary: Choice D is correct as it promotes safety by preventing burns through proactive measures. Choices A, B, and C are incorrect as they encourage unsafe practices that can increase the risk of burns and scalds.
The natural cycle relating to body functions that occurs due to daily, monthly or yearly changes is called
- A. Biofuel
- B. Biology
- C. Biodiversity
- D. Biorhythm
Correct Answer: D
Rationale: The correct answer is D: Biorhythm. Biorhythm refers to the natural cycle of body functions that occur due to daily, monthly, or yearly changes. This term is specific to the biological rhythms that regulate various physiological processes in living organisms.
A: Biofuel - Biofuel is not related to the natural cycle of body functions. It refers to renewable energy sources derived from living organisms.
B: Biology - While biology is the study of living organisms and their interactions, it does not specifically refer to the natural cycles of body functions.
C: Biodiversity - Biodiversity refers to the variety of life forms in a particular ecosystem and is not directly related to the natural cycles of body functions.
In summary, biorhythm is the correct answer as it directly pertains to the natural cycles of body functions, while the other choices are unrelated terms in the context of this question.
