Which system is primarily affected by tuberculosis (Mycobacterium)?
- A. stomach (GI)
- B. heart (cardiac)
- C. lungs (respiratory)
- D. skin (integumentary)
Correct Answer: C
Rationale: Tuberculosis, caused by Mycobacterium tuberculosis, primarily affects the respiratory system. This aerobic bacillus thrives in highly oxygenated body sites, such as the lungs, growing ends of bones, and the brain. The bacillus is airborne, making the lungs a common site for infection. Choices A, B, and D are incorrect as tuberculosis predominantly impacts the respiratory system and rarely involves the stomach, heart, or skin.

A young female teenager describes a brutal assault and rape to the nurse on duty. Which of the following actions should the nurse take first?
- A. Check with the case manager on duty about possible police intervention.
- B. Provide an environment of concern and emotional stabilization.
- C. Clean the patient's wounds with normal saline and gauze.
- D. Refer the patient to a counselor specializing in trauma.
Correct Answer: B
Rationale: In a situation where a patient describes a brutal assault and rape, the first priority should be to provide emotional support and create a safe and supportive environment. This helps the patient feel secure and cared for, which is crucial for their well-being at that moment. Checking with the case manager about police intervention should come after ensuring the patient's immediate emotional needs are addressed. Cleaning the patient's wounds, though important, can be secondary to providing emotional stabilization. Referring the patient to a counselor specializing in trauma is also crucial for long-term support, but the immediate focus should be on providing emotional support and stability.
What is one characteristic of human immunodeficiency virus (HIV)?
- A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
- B. HIV replication occurs intracellularly.
- C. HIV integrates its genetic material into the host cell's DNA.
- D. DNA replication is irrelevant to HIV.
Correct Answer: C
Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.
A client who has a known history of cardiac problems and is still smoking enters the clinic complaining of sudden onset of sharp, stabbing pain that intensifies with a deep breath. The pain is occurring on only one side and can be isolated upon general assessment. The nurse concludes that this description is most likely caused by:
- A. pleurisy.
- B. pleural effusion.
- C. atelectasis.
- D. tuberculosis.
Correct Answer: A
Rationale: Pleurisy is an inflammation of the pleura and is often accompanied by an abrupt onset of pain. Symptoms of pleurisy include sudden sharp, stabbing pain that is usually unilateral and localized to a specific portion of the chest. The pain can be exacerbated by deep breathing. In contrast, pleural effusion is characterized by fluid accumulation in the pleural space, not sharp pain. Atelectasis involves collapse or closure of a lung leading to reduced gas exchange, but it does not typically present with sharp, stabbing pain. Tuberculosis is a bacterial infection that can affect the lungs but does not typically manifest with sudden sharp pain exacerbated by deep breathing.
Clomiphene is prescribed for a female client to treat infertility. The nurse is providing information to the client and her spouse about the medication and provides the couple with which information?
- A. If the oral tablets are not successful, the medication will be administered intravenously.
- B. The couple should engage in coitus at least every other day during treatment.
- C. The physician should be notified immediately if breast engorgement occurs.
- D. Multiple births occur in a small percentage of clomiphene-facilitated pregnancies.
Correct Answer: D
Rationale: The correct answer is that multiple births (usually twins) occur in a small percentage (8% - 10%) of clomiphene-facilitated pregnancies. The couple should be informed about this potential outcome. Clomiphene is available in 50-mg tablets for oral use; there is no intravenous form of the medication. Breast engorgement is a common side effect of clomiphene that typically resolves after discontinuation of the medication. Ovulation usually happens 5 to 10 days after the last dose of clomiphene, and the couple is advised to engage in coitus at least every other day during this time. Therefore, choices A, B, and C are incorrect as they do not provide accurate information regarding clomiphene treatment for infertility.
A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?
- A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
- B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
- C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
- D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
Correct Answer: A
Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.
