Biology Practice Test
1. Which of the following organelles is known as the cell's transportation center?
- A. Golgi apparatus
- B. Endoplasmic reticulum
- C. Mitochondria
- D. Lysosomes
Correct answer: B
Rationale: The correct answer is B, Endoplasmic reticulum. The endoplasmic reticulum is involved in the synthesis and transport of proteins and lipids within the cell. The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids for transport. Mitochondria are known as the powerhouse of the cell, producing energy in the form of ATP. Lysosomes are involved in the digestion and recycling of cellular waste.
2. In the change-of-shift report, the nurse is told that a client has a Stage 2 pressure ulcer. Which ulcer appearance is most likely to be observed?
- A. Shallow open ulcer with a red-pink wound bed.
- B. A deep pocket of infection and necrotic tissues.
- C. An area of erythema that is painful to touch.
- D. Visible subcutaneous tissue with sloughing.
Correct answer: A
Rationale: A Stage 2 pressure ulcer typically presents as a shallow open ulcer with a red-pink wound bed. This appearance is characteristic of a Stage 2 pressure ulcer where there is partial thickness skin loss involving the epidermis and possibly the dermis. Choice B, a deep pocket of infection and necrotic tissues, is more indicative of a Stage 3 or Stage 4 pressure ulcer where the ulcer extends into deeper tissue layers. Choice C, an area of erythema that is painful to touch, is more commonly seen in early-stage pressure ulcers such as Stage 1. Choice D, visible subcutaneous tissue with sloughing, is characteristic of a more severe stage of pressure ulcer beyond Stage 2.
3. A client is being treated with a tricyclic antidepressant (TCA). Which side effect should the nurse monitor for?
- A. Constipation and urinary retention.
- B. Increased appetite and weight loss.
- C. Sedation and blurred vision.
- D. Insomnia and dry mouth.
Correct answer: A
Rationale: The correct answer is A: Constipation and urinary retention. Tricyclic antidepressants (TCAs) are known to have anticholinergic side effects, which include constipation and urinary retention. These side effects occur due to the inhibition of cholinergic receptors, leading to decreased gastrointestinal motility and relaxation of the detrusor muscle in the bladder. Choices B, C, and D are incorrect because increased appetite, weight loss, sedation, blurred vision, insomnia, and dry mouth are not typically associated with the use of TCAs. Monitoring for constipation and urinary retention is essential to prevent complications and ensure the client's safety.
4. A client with a history of severe rheumatoid arthritis is receiving a corticosteroid. Which assessment finding should the nurse report to the healthcare provider immediately?
- A. Blood glucose level of 180 mg/dL
- B. Weight gain of 2 pounds in 24 hours
- C. Blood pressure of 140/90 mmHg
- D. Increased joint pain
Correct answer: C
Rationale: Elevated blood pressure (140/90 mmHg) is a significant finding that the nurse should report immediately. Hypertension can be a severe side effect of corticosteroid therapy, especially in clients with preexisting conditions like rheumatoid arthritis. It requires prompt intervention to prevent complications such as cardiovascular events. The other options, while important to monitor, are not as critical as elevated blood pressure in this context. A blood glucose level of 180 mg/dL may indicate hyperglycemia, weight gain could be due to fluid retention, and increased joint pain is expected in a client with severe rheumatoid arthritis.
5. A nurse is collecting data from a client who has hypocalcemia. Which of the following findings should the nurse expect?
- A. Decreased deep-tendon reflexes
- B. Skeletal muscle weakness
- C. Hypoactive bowel sounds
- D. Tingling of the lips
Correct answer: D
Rationale: The correct answer is D, tingling of the lips (perioral tingling). This is a common symptom of hypocalcemia due to increased neuromuscular excitability. Choice A, decreased deep-tendon reflexes, is more indicative of hypercalcemia. Choice B, skeletal muscle weakness, is associated with hypokalemia. Choice C, hypoactive bowel sounds, is not a typical finding in hypocalcemia.
