What is the most appropriate action for a client with a history of asthma who is experiencing wheezing?

Correct Answer: A

Rationale: The correct answer is A: Administer albuterol. Albuterol is a bronchodilator that helps open the airways, relieving wheezing in asthma patients. It is the first-line treatment for acute asthma exacerbations. Antihistamines (B) do not treat asthma symptoms. Monitoring for infection (C) is important but not the immediate action for wheezing. Epinephrine (D) is used for severe allergic reactions, not routine asthma management.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure measurement. Dizziness and weakness can be symptoms of hypotension or low blood pressure. Prioritizing blood pressure measurement is crucial because it can indicate if the patient is at risk of complications like cardiovascular collapse. Pulse oximetry (B) is important for assessing oxygen levels in the blood but may not directly address dizziness and weakness. Blood glucose levels (C) are important but not the priority in this scenario. Cardiac monitoring (D) may be necessary but should come after assessing blood pressure to rule out immediate life-threatening conditions.

Correct Answer: B

Rationale: The correct answer is B: Clanging. Clanging refers to the phenomenon where words are chosen based on sound rather than meaning. In this case, the patient's speech demonstrates a pattern of words that rhyme or have similar sounds, despite lacking coherence or logical connection. This behavior is commonly seen in individuals with conditions like schizophrenia. Incorrect choices: A: Blocking - Blocking refers to sudden interruption or cessation of speech. This does not apply to the scenario described. C: Echolalia - Echolalia involves repetition of words or phrases spoken by others, not self-generated word patterns like in the scenario. D: Neologism - Neologism refers to the creation of new words or phrases with unique meanings, which is not reflected in the patient's speech pattern.

Correct Answer: C

Rationale: The correct answer is C: Shortness of breath and chest pain. This is most concerning because it could indicate a pulmonary embolism, a serious complication of DVT where a blood clot travels to the lungs. Shortness of breath and chest pain are signs of compromised respiratory and cardiac function. A: Pain and swelling in the leg are common symptoms of DVT but not as concerning as symptoms of a pulmonary embolism. B: Redness and warmth around the affected area are typical signs of inflammation associated with DVT but do not indicate a life-threatening complication like a pulmonary embolism. D: Pale skin and decreased pulse in the affected leg could be signs of compromised circulation due to DVT, but they are not as immediately life-threatening as symptoms of a pulmonary embolism.

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 antibiotics. Antibiotics are crucial in treating sepsis as they help to fight the underlying infection causing the condition. Administering antibiotics promptly can prevent the infection from spreading and worsening. Fluids (choices B and C) are important for treating sepsis to maintain blood pressure and support organ function, but antibiotics are the primary intervention to target the infection. Administering oxygen (choice D) may be necessary to support respiratory function in septic patients, but it is not the most effective action to address the underlying infection.

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: C

Rationale: Rationale for Correct Answer (C): Promoting activity is the most prioritized nursing intervention for a client with CHF. Activity helps improve cardiac function, decreases fluid accumulation, and enhances overall cardiovascular health. It also prevents complications like muscle weakness and deconditioning. It is crucial in managing CHF symptoms and improving the client's quality of life. Summary of Incorrect Choices: A: Administering diuretics helps in reducing fluid overload but does not address the underlying issue of improving cardiac function through physical activity. B: Limiting fluid intake is important, but promoting activity takes precedence as it directly impacts cardiac function and fluid accumulation. D: Maintaining fluid balance is necessary but is a broad concept that includes various interventions, with promoting activity being more focused and critical in CHF management.

Correct Answer: A

Rationale: The correct answer is A because tolerance is a physiological phenomenon where the body adapts to a drug, requiring higher doses for the same effect. This is a common occurrence with opioids in chronic pain management. Choice B is incorrect as it refers to drug-seeking behavior, not tolerance. Choice C is incorrect because addiction and physical dependence are different concepts. Choice D is incorrect as it relates to a specific scenario of substance abuse alongside chronic pain, not the mechanism behind the need for increased opioid doses in chronic pain management.
