1. What is a muscular enlarged pouch or sac that lies slightly to the left and is used for the temporary storage of food?
- A. Gallbladder
- B. Urinary bladder
- C. Stomach
- D. Lungs
Correct answer: C
Rationale: The correct answer is the stomach. The stomach is a muscular organ located slightly to the left in the abdominal cavity. It serves as a temporary storage site for food where it is mixed with digestive enzymes and acids to begin the process of digestion. The gallbladder (Choice A) is not involved in food storage; it stores bile produced by the liver. The urinary bladder (Choice B) is part of the urinary system and stores urine. The lungs (Choice D) are responsible for respiration, not food storage.
2. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. aPTT
- C. INR
- D. Platelet count
Correct answer: B
Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.
3. A patient is being treated with hormone replacement therapy (HRT) for menopausal symptoms. What are the risks associated with long-term HRT that the nurse should discuss with the patient?
- A. HRT may increase the risk of cardiovascular events and breast cancer.
- B. HRT may decrease the risk of osteoporosis.
- C. HRT may increase the risk of venous thromboembolism.
- D. HRT may improve mood and energy levels.
Correct answer: A
Rationale: The correct answer is A. Long-term HRT is associated with increased risks of cardiovascular events and breast cancer. These risks should be discussed with the patient to ensure they are informed about the potential adverse effects. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it may increase the risk of certain conditions like cardiovascular events. Choice C is incorrect as HRT is associated with an increased risk of venous thromboembolism, not a decreased risk. Choice D is incorrect because while HRT may have positive effects like improving symptoms of menopause, it is not primarily indicated for improving mood and energy levels.
4. A nurse is completing an admission assessment for a client who reports vomiting and diarrhea for the past 3 days. Which of the following findings should the nurse expect?
- A. Blood pressure 144/82 mm Hg
- B. Urine specific gravity 1.03
- C. Neck vein distention
- D. Urine specific gravity 1.01
Correct answer: A
Rationale: In a client experiencing vomiting and diarrhea, the nurse should expect findings such as dehydration, which can lead to hypovolemia and subsequent increased heart rate and decreased blood pressure. A blood pressure of 144/82 mm Hg is indicative of possible dehydration in this client. Urine specific gravity is typically increased in dehydrated individuals, so choices B and D are incorrect. Neck vein distention is not a typical finding associated with vomiting and diarrhea; therefore, choice C is also incorrect.
5. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?
- A. Ionic bond
- B. Covalent bond
- C. Functional group
- D. Metallic bond
Correct answer: A
Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.
