1. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is experiencing respiratory alkalosis due to hyperventilation. Hyperventilation leads to excessive loss of carbon dioxide, causing a decrease in hydrogen ion concentration and an increase in pH levels. Choices A, C, and D are incorrect. Respiratory acidosis is characterized by high PaCO2 and low pH. Metabolic acidosis is associated with low HCO3- levels and low pH. Metabolic alkalosis is marked by high HCO3- levels and high pH. In this case, the ABG results indicate respiratory alkalosis.

2. What are the expected manifestations of a thrombotic stroke?

A. Gradual loss of function on one side of the body
B. Loss of sensation in the affected extremity
C. Sudden loss of consciousness
D. Seizures and convulsions

Correct answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. Thrombotic strokes are caused by a clot forming in a blood vessel supplying the brain, leading to a gradual onset of symptoms due to impaired blood flow to specific brain regions. Choices B, C, and D are incorrect because loss of sensation, sudden loss of consciousness, seizures, and convulsions are not typically associated with thrombotic strokes. In a thrombotic stroke, the symptoms develop slowly over time, often over minutes to hours, and include manifestations such as weakness, numbness, or paralysis on one side of the body, along with other symptoms related to the affected brain area.

3. What is the priority action for a patient experiencing chest pain from acute coronary syndrome?

A. Administer sublingual nitroglycerin
B. Obtain IV access
C. Check the patient's cardiac enzymes
D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. Nitroglycerin helps relieve chest pain by dilating blood vessels and improving blood flow to the heart, which is crucial in managing acute coronary syndrome. While obtaining IV access and checking cardiac enzymes are important steps in the assessment and management of acute coronary syndrome, administering nitroglycerin takes precedence to alleviate symptoms and reduce cardiac tissue damage. Administering aspirin is also essential in the treatment of acute coronary syndrome, but it is not the immediate priority in this scenario.

4. What precaution should be advised to patients following cataract surgery?

A. Wear dark glasses while outdoors
B. Use warm compresses
C. Avoid NSAIDs
D. Avoid bright lights

Correct answer: A

Rationale: Patients who have undergone cataract surgery should wear dark glasses when outdoors to shield their eyes from light exposure, which can be uncomfortable or harmful during the recovery period. Using warm compresses (choice B) is not typically recommended after cataract surgery as it's more relevant for certain eye conditions. Avoiding NSAIDs (choice C) is advised to prevent bleeding complications, but it is not directly related to eye protection post-surgery. While avoiding bright lights (choice D) is crucial, wearing dark glasses provides a practical solution to achieve this, making choice A the most appropriate precaution.

5. A nurse is teaching a group of clients about the risk factors for osteoporosis. Which of the following should the nurse include as a risk factor for osteoporosis?

A. Early menopause
B. History of falls
C. African American race
D. Obesity

Correct answer: A

Rationale: The correct answer is A: Early menopause. A client who goes into early menopause, from natural or surgical causes, is at a greater risk for developing osteoporosis due to the rapid drop in estrogen levels. Choice B, history of falls, is not a direct risk factor for osteoporosis but rather a risk for fractures related to osteoporosis. Choice C, African American race, is actually associated with a lower risk of osteoporosis. Choice D, obesity, is considered a protective factor against osteoporosis as excess weight can provide additional support to bones.
