What term describes excessive stretching of a ligament, as seen in a client with a pulled ligament?

Correct Answer: B

Rationale: The correct answer is B: strain. A strain refers to excessive stretching or tearing of a muscle or tendon, not a ligament. A sprain (choice A) is the correct term for excessive stretching of a ligament. Subluxation (choice C) refers to partial dislocation of a joint, not a ligament injury. Distortion (choice D) is a general term that does not specifically describe ligament stretching. Therefore, the correct term for excessive stretching of a ligament is a sprain, making choice A the correct answer.

Correct Answer: B

Rationale: Acyclovir is a nucleoside analog antiviral drug that is specifically effective against herpes simplex virus (HSV) types 1 and 2, as well as varicella-zoster virus (VZV). The drug works by inhibiting viral DNA synthesis. HSV and VZV are both members of the herpes virus family, and acyclovir is most commonly prescribed for infections caused by these viruses. Therefore, the correct answer is B. Choice A (HIV) is incorrect because acyclovir is not effective against HIV. Choice C (CMV) is incorrect because acyclovir is less effective against cytomegalovirus (CMV) compared to HSV and VZV. Choice D (influenza A viruses) is incorrect because acyclovir is not indicated for the treatment of influenza viruses.

Correct Answer: A

Rationale: The correct answer is A: Administer antiemetics. Antiemetics help alleviate nausea and vomiting by blocking neurotransmitters in the brain. This intervention directly targets the symptoms and provides relief for the client. Administering fluids (B) may help with hydration but does not address the root cause. Administering analgesics (C) is for pain relief, not for nausea and vomiting. Monitoring electrolytes (D) is important but does not directly treat the symptoms. Therefore, administering antiemetics is the most appropriate intervention for severe nausea and vomiting.

Correct Answer: A

Rationale: The correct answer is A: Assess vital signs. Vital signs provide crucial information on the client's overall condition and can help identify any life-threatening issues. Monitoring vital signs such as blood pressure, heart rate, respiratory rate, and temperature can guide immediate interventions and determine the urgency of further assessments or treatments. Administering oxygen (B) would be appropriate after assessing vital signs. Performing an ECG (C) may be indicated later but is not the priority in this acute situation. Monitoring serum glucose levels (D) is not typically the first assessment in a client with severe abdominal pain.

Correct Answer: D

Rationale: The correct answer is D: Lupus. Lupus can affect the kidneys, leading to renal impairment. Renal impairment can decrease the body's ability to excrete ammonia, resulting in elevated levels. Renal failure (choice A) can also lead to elevated ammonia levels, but lupus specifically contributes to renal issues. Cirrhosis (choice B) primarily affects the liver, not kidneys. Psoriasis (choice C) is a skin condition and does not directly impact ammonia levels.

Correct Answer: A

Rationale: The correct answer is A: variable decelerations. Variable decelerations are abrupt decreases in fetal heart rate that vary in depth, duration, and timing, which can indicate cord compression. The variability in these decelerations suggests that the umbilical cord is being compressed intermittently. Early decelerations (B) are usually caused by head compression during contractions and mirror the contractions, not indicating cord compression. Bradycardia (C) is a slow heart rate, which can be caused by various factors but is not specific to cord compression. Tachycardia (D) is a fast heart rate, which can also be caused by various factors but is not typically associated with cord compression.

Correct Answer: B

Rationale: The correct answer is B because conveying respect for differences helps build trust and encourages patients to share their perspectives openly. This fosters a positive patient-provider relationship and enhances communication. Choice A is incorrect as patients have unique behaviors. Choice C is incorrect as cultural expectations do not fully explain individual differences. Choice D is incorrect as expressing one's culture is not solely dependent on exposure to Canadian values.

Correct Answer: A

Rationale: The correct answer is A: Inspect for visible pulsation. This is because an arteriovenous fistula for hemodialysis should have a visible pulsation, indicating proper blood flow. Palpating for thrill (B) and auscultating for bruit (C) are also common assessments for an arteriovenous fistula, but inspecting for visible pulsation is the most direct and reliable way to assess the patency of the fistula. Percussing for dullness (D) is not relevant in this context as it does not provide information about the vascular access site.

Correct Answer: C

Rationale: The correct answer is C: sodium and chloride. In the extracellular fluid, sodium and chloride are the major electrolytes due to their roles in maintaining fluid balance, nerve function, and muscle contraction. Potassium and phosphate (choice B) are primarily found in intracellular fluid, while potassium and chloride (choice A) are not the major electrolytes in extracellular fluid. Similarly, sodium and phosphate (choice D) are not major extracellular electrolytes. Thus, choice C is the correct answer based on the significant presence and functions of sodium and chloride in the extracellular fluid.
