1. A client is being taught about the use of enoxaparin (Lovenox) for the prevention of deep vein thrombosis. Which instruction should the nurse include in the teaching plan?
- A. Inject the medication subcutaneously.
- B. Avoid massaging the injection site after administration.
- C. Administer the medication at the same time each day.
- D. Do not expel the air bubble from the syringe before injection.
Correct answer: C
Rationale: Enoxaparin (Lovenox) is administered subcutaneously at the same time each day to maintain consistent blood levels. Injecting the medication into the muscle is incorrect, as it should be given subcutaneously. Massaging the injection site should be avoided to prevent bruising. The air bubble in the prefilled syringe should not be expelled, as it ensures the full dose is administered.
2. A client with chronic renal failure (CRF) is placed on a protein-restricted diet. Which nutritional goal supports this dietary change?
- A. Reduce production of urea nitrogen (BUN)
- B. Decrease the risk of hyperkalemia
- C. Promote healing of injured nephrons
- D. Promote the elimination of albumin
Correct answer: A
Rationale: The correct answer is A: Reduce production of urea nitrogen (BUN). A protein-restricted diet is essential for clients with chronic renal failure to decrease the production of urea nitrogen, as the kidneys cannot effectively excrete it. This helps in managing the accumulation of waste products in the body. Choices B, C, and D are incorrect. Choice B is not directly related to a protein-restricted diet but focuses on managing potassium levels. Choice C is not a direct nutritional goal of a protein-restricted diet but aims at supporting kidney function. Choice D is not a target of a protein-restricted diet but relates more to managing protein loss in the urine.
3. Which of the following is a primary goal of nursing?
- A. Assist patients in achieving a peaceful death.
- B. Enhance personal knowledge and skills to improve patient outcomes.
- C. Champion quality of life over quantity of life.
- D. Manage costs to enhance patients' quality of life.
Correct answer: A
Rationale: The primary goal of nursing is to assist patients in achieving a peaceful death if recovery is not feasible. This involves providing comfort, dignity, and support during the end-of-life process. Choice B is incorrect because while improving personal knowledge and skills is important, it is not the primary goal of nursing. Choice C, advocating for quality of life over quantity of life, is a valid aspect of nursing care but may not always be the primary goal. Choice D, managing costs to enhance patients' quality of life, is not a primary goal of nursing, as the focus should primarily be on patient care and well-being, rather than financial considerations.
4. The nurse is caring for a patient who is ordered to receive PO trimethoprim-sulfamethoxazole (TMP-SMX) 160/800 QID to treat a urinary tract infection caused by E. coli. The nurse will contact the provider to clarify the correct
- A. dose.
- B. drug.
- C. frequency.
- D. route.
Correct answer: C
Rationale: The correct answer is 'frequency.' Trimethoprim-sulfamethoxazole (TMP-SMX) is typically prescribed to be taken twice daily, not four times a day (QID). The dose, drug, and route are already specified in the order, so the nurse should contact the provider to clarify the frequency of administration to ensure optimal treatment for the urinary tract infection caused by E. coli. Choosing 'dose' is incorrect because the dose of 160/800 is already provided in the order. 'Drug' is incorrect because the medication Trimethoprim-sulfamethoxazole (TMP-SMX) is explicitly stated in the prescription. 'Route' is incorrect as PO (by mouth) is also clearly indicated in the prescription.
5. What is the most important function of carbohydrates?
- A. Store and provide energy for the body
- B. Create amino acids
- C. Maintain body temperature
- D. Insulate body organs against shock
Correct answer: A
Rationale: The most important function of carbohydrates is to store and provide energy for the body through metabolic processes. Carbohydrates are broken down into glucose, which is used as the primary source of energy for various cellular functions. Choice B is incorrect because amino acids are the building blocks of proteins, not directly created by carbohydrates. Choice C is incorrect as the regulation of body temperature is primarily controlled by mechanisms such as sweating and shivering, not carbohydrates. Choice D is incorrect as insulation of body organs against shock is mainly provided by adipose tissue, not carbohydrates.
