1. What is the main function of the mitochondria in a cell?

• A. To produce energy in the form of ATP
• B. To synthesize proteins
• C. To store genetic information
• D. To regulate cell growth

Correct answer: A

Rationale: The correct answer is A: To produce energy in the form of ATP. Mitochondria are known as the powerhouse of the cell because they are responsible for producing energy in the form of ATP through a process called cellular respiration. This energy is essential for various cellular activities. Choice B is incorrect because protein synthesis primarily occurs in the ribosomes. Choice C is incorrect as the genetic information is stored in the cell's nucleus. Choice D is incorrect as the regulation of cell growth involves various other organelles and processes within the cell.

2. A patient is prescribed estradiol (Estrace) for hormone replacement therapy. What should the nurse monitor during this therapy?

• A. Blood pressure
• B. Blood glucose levels
• C. Liver function tests
• D. Kidney function tests

Correct answer: C

Rationale: During estradiol therapy, the nurse should monitor liver function tests. Estradiol can potentially impact liver function, making it essential to assess for any signs of liver dysfunction. Monitoring blood pressure (Choice A) is not directly related to estradiol therapy. While blood glucose levels (Choice B) should be monitored in patients taking certain medications like corticosteroids or antipsychotics, it is not typically necessary for patients on estradiol therapy. Kidney function tests (Choice D) are not the priority for monitoring during estradiol therapy, as the liver is more commonly affected.

3. A client with a history of smoking presents with a chronic cough and shortness of breath. The nurse should suspect which condition?

• A. Pulmonary fibrosis
• B. Chronic obstructive pulmonary disease (COPD)
• C. Lung cancer
• D. Pulmonary edema

Correct answer: B

Rationale: The correct answer is B: Chronic obstructive pulmonary disease (COPD). COPD is often associated with a chronic cough and shortness of breath, especially in individuals with a history of smoking. Pulmonary fibrosis (choice A) typically presents with progressive dyspnea and dry cough. Lung cancer (choice C) may present with a chronic cough, shortness of breath, and other symptoms like weight loss and hemoptysis. Pulmonary edema (choice D) presents with symptoms such as acute shortness of breath, orthopnea, and pink, frothy sputum.

4. Which of the following describes passive immunity?

• A. Vaccination against the disease
• B. Transfer of antibodies from mother to baby
• C. Cuts or wounds that are infected and heal
• D. Having the disease in question

Correct answer: B

Rationale: Passive immunity is the transfer of pre-formed antibodies from one individual to another, providing immediate but temporary protection. In this case, the correct answer is the transfer of antibodies from the mother to the baby, as it describes the concept of passive immunity. Choice A, vaccination against the disease, refers to active immunity where the individual's immune system is stimulated to produce antibodies. Choice C, cuts or wounds that are infected and heal, is unrelated to immunity. Choice D, having the disease in question, does not describe passive immunity but rather acquiring active immunity through exposure to the pathogen.

5. A woman has been prescribed Climara, a transdermal estradiol patch. Which of the following should she be instructed by the nurse regarding the administration?

• A. Avoid prolonged sun exposure at the patch site due to increased plasma concentrations.
• B. The application of heat at the patch site will decrease effectiveness and result in pregnancy.
• C. The medication, when exposed to sunlight, can increase the risk of breast cancer.
• D. Exposure of the medication to occasional cold will increase effectiveness with application.

Correct answer: A

Rationale: The correct answer is A. The Climara patch delivers estradiol transdermally, and patients should be instructed to avoid prolonged sun exposure at the patch site due to increased plasma concentrations. Sun exposure can accelerate the absorption of the medication, leading to higher systemic levels than intended. Choices B, C, and D are incorrect because heat at the patch site does not result in pregnancy but may alter absorption rates, there is no direct link between sunlight exposure and breast cancer risk related to this medication, and exposure to cold does not increase effectiveness of the transdermal patch.
