Biology Practice Test
1. Which two items react during cellular respiration?
- A. Glucose and water
- B. Carbon dioxide and water
- C. Carbon dioxide and oxygen
- D. Glucose and oxygen
Correct answer: D
Rationale: The correct answer is D: Glucose and oxygen. During cellular respiration, glucose and oxygen react in the presence of enzymes to produce carbon dioxide, water, and energy in the form of ATP. Choice A (Glucose and water) is incorrect because water is a product of cellular respiration, not a reactant. Choice B (Carbon dioxide and water) is incorrect as carbon dioxide is produced during cellular respiration, not a reactant. Choice C (Carbon dioxide and oxygen) is incorrect because oxygen is a reactant in cellular respiration, not a product.
2. The client with chronic kidney disease (CKD) is being taught about the necessary sodium restriction in the diet to prevent edema and hypertension. Which statement by the client indicates more teaching is needed?
- A. I am thrilled that I can continue to eat fast food.
- B. I will cut out bacon with my eggs every morning.
- C. My cooking style will change by not adding salt.
- D. I will probably lose weight by cutting out potato chips.
Correct answer: A
Rationale: Choice A, 'I am thrilled that I can continue to eat fast food,' indicates a lack of understanding as fast food is typically high in sodium, which is detrimental for individuals with CKD. The client should be advised to avoid fast food due to its high sodium content. Choices B, C, and D demonstrate a good understanding of the need for sodium restriction in the diet to prevent complications associated with CKD. Cutting out bacon, avoiding salt in cooking, and eliminating high-sodium snacks like potato chips are all positive steps towards managing CKD.
3. A client with end-stage renal disease (ESRD) is receiving hemodialysis. Which laboratory value should the nurse monitor closely?
- A. Serum calcium level of 9 mg/dl
- B. Serum potassium level of 4.5 mEq/L
- C. Serum creatinine level of 2.0 mg/dl
- D. Serum sodium level of 138 mEq/L
Correct answer: C
Rationale: The correct answer is C: Serum creatinine level of 2.0 mg/dl. In a client with ESRD receiving hemodialysis, serum creatinine should be closely monitored. Elevated creatinine levels indicate impaired kidney function. Monitoring serum calcium levels (Choice A), serum potassium levels (Choice B), and serum sodium levels (Choice D) is also important in clients with ESRD, but the most crucial indicator of kidney function in this case is serum creatinine.
4. A client receiving total parenteral nutrition (TPN) is experiencing nausea and vomiting. What is the nurse's first action?
- A. Check the client's blood glucose level.
- B. Decrease the rate of TPN infusion.
- C. Administer an antiemetic as prescribed.
- D. Check the client's TPN bag for solution accuracy.
Correct answer: D
Rationale: The correct first action for the nurse to take when a client receiving TPN is experiencing nausea and vomiting is to check the client's TPN bag for solution accuracy. This is crucial to ensure that the correct solution is being administered and to address any potential errors. Checking the blood glucose level or administering an antiemetic may be necessary interventions but addressing the TPN bag's accuracy should be the priority to prevent any complications related to incorrect TPN solution.
5. A male client with schizophrenia is admitted to the mental health unit after abruptly stopping his prescription for ziprasidone (Geodon) one month ago. Which question is most important for the nurse to ask the client?
- A. Have you lost interest in activities you used to enjoy?
- B. Has your ability to think or concentrate decreased?
- C. How many consecutive hours do you sleep at night?
- D. Do you hear sounds or voices that others do not hear?
Correct answer: D
Rationale: Inquiring about hallucinations is crucial for assessing the return of psychotic symptoms due to discontinuation of antipsychotic medication. Hearing sounds or voices that others do not hear can indicate the presence of auditory hallucinations, a common symptom in schizophrenia. Choices A, B, and C are important aspects to assess in clients with schizophrenia, but in this scenario, the priority is to determine if the client is experiencing hallucinations, which can be a sign of worsening psychotic symptoms.
