1. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

2. When teaching a client about managing hypertension, what dietary advice should be emphasized?

• A. Reduce sodium intake
• B. Increase potassium intake
• C. Limit alcohol consumption
• D. All of the above

Correct answer: D

Rationale: When managing hypertension, it is crucial to adopt comprehensive dietary changes. This includes reducing sodium intake to help lower blood pressure, increasing potassium intake to counteract the effects of sodium and help regulate blood pressure, and limiting alcohol consumption as excessive alcohol can raise blood pressure. Therefore, emphasizing all the options provided (A, B, and C) is essential in effectively managing hypertension and reducing overall cardiovascular risk. Choices A, B, and C are not individually sufficient as a single dietary modification but collectively work together to support blood pressure management.

3. When assisting a client to obtain a sputum specimen, the nurse observes the client cough and spit a large amount of frothy saliva in the specimen collection cup. What action should the nurse implement next?

• A. Advise the client that suctioning will be used to obtain another specimen
• B. Re-instruct the client in coughing techniques to obtain another specimen
• C. Provide the client a glass of water and mouthwash to rinse the mouth
• D. Label the container and place the container in a biohazard transport bag

Correct answer: C

Rationale: After observing the client cough and produce frothy saliva in the collection cup, the nurse should provide the client with a glass of water and mouthwash to rinse the mouth. This action helps clear the mouth of contaminants, ensuring a more accurate sputum specimen for diagnostic testing. Option A is incorrect because suctioning is not the appropriate next step in this situation. Option B is unnecessary as re-instructing the client in coughing techniques may not address the immediate issue of contaminated saliva in the specimen. Option D is premature since labeling and transporting the container should only be done after obtaining a valid specimen.

4. What is the function of the cervix in reproduction?

• A. Accepts and interprets signals of sexual stimuli
• B. Secretes mucus to facilitate sperm transport
• C. Serves as the site for union of ovum and sperm
• D. Receives the penis during intercourse

Correct answer: B

Rationale: The cervix functions in reproduction by secreting mucus that facilitates the transport of sperm to the uterus. Choice A is incorrect because the cervix does not interpret signals of sexual stimuli. Choice C is incorrect as the site for the union of ovum and sperm is the fallopian tube. Choice D is incorrect as the cervix is not involved in receiving the penis during intercourse.

5. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Avoid foods high in vitamin K
• C. Increase intake of foods rich in vitamin C
• D. Limit intake of dairy products

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
