1. Which physiologic mechanism best describes the function of the sodium-potassium pump?
- A. active transport
- B. diffusion
- C. filtration
- D. osmosis
Correct answer: A
Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.
2. A nurse is assessing an 18-year-old female who has recently suffered a TBI. The nurse notes a slower pulse and impaired respiration. The nurse should report these findings immediately to the physician due to the possibility the patient is experiencing which of the following conditions?
- A. Increased intracranial pressure
- B. Increased function of cranial nerve X
- C. Sympathetic response to activity
- D. Meningitis
Correct answer: A
Rationale: The nurse should report the slower pulse and impaired respiration to the physician immediately as they are indicative of increased intracranial pressure (ICP) following a traumatic brain injury (TBI). These signs suggest that there may be a rise in pressure within the skull, which can be a life-threatening condition requiring urgent intervention. Options B and C are unlikely in this scenario as they do not correlate with the symptoms presented. Meningitis (Option D) typically presents with different signs and symptoms, such as fever, headache, and neck stiffness, which are not described in the patient's case.
3. Jane Love, a 35-year-old gravida III para II at 23 weeks gestation, is seen in the Emergency Department with painless, bright red vaginal bleeding. Jane reports that she has been feeling tired and has noticed ankle swelling in the evening. Laboratory tests reveal a hemoglobin level of 11.5 g/dL. After evaluating the situation, the nurse determines that Jane is at risk for placenta previa, based on which of the following data?
- A. anemia
- B. edema
- C. painless vaginal bleeding
- D. fatigue
Correct answer: C
Rationale: Placenta previa is a disorder where the placenta implants in the lower uterine segment, causing painless bleeding in the third trimester of pregnancy. The bleeding results from tearing of the placental villi from the uterine wall as the lower uterine segment contracts and dilates. It can be slight or profuse and can include bright red, painless bleeding. While anemia (choice A) may be a consequence of chronic bleeding from placenta previa, it is not a direct indicator. Edema (choice B) and fatigue (choice D) are nonspecific symptoms that can occur in pregnancy but are not specific to placenta previa.
4. When teaching bleeding precautions to a client with leukemia, the PN should include which of the following instructions?
- A. Use a soft toothbrush.
- B. Use dental floss daily.
- C. Hold pressure on any scrapes for 1-2 minutes.
- D. Use a triple-edged razor.
Correct answer: A
Rationale: The correct answer is to 'Use a soft toothbrush.' A soft toothbrush is recommended because it is less likely to cause the gums to bleed in clients with leukemia, who are at risk of bleeding due to overcrowding of white cells at the expense of other cell types like platelets. Choice B, 'Use dental floss daily,' is incorrect because dental floss is contraindicated and can make the gums bleed in clients with leukemia. Choice C, 'Hold pressure on any scrapes for 1-2 minutes,' is incorrect because when clotting is impaired, pressure should be held for 5-10 minutes or longer until the bleeding stops. Choice D, 'Use a triple-edged razor,' is incorrect because an electric razor should be used instead of a triple-edged razor to prevent small cuts and bleeding in clients with leukemia.
5. A nurse is returning phone calls in a pediatric clinic. Which of the following reports most requires the nurse's immediate attention and phone call?
- A. An 8-year-old boy has been vomiting, appears to have slower movements, and has a history of an atrioventricular shunt placement.
- B. A 10-year-old girl feels a dull pain in her abdomen after doing sit-ups in gym class.
- C. A 7-year-old boy has been having a low fever and headache for the past 3 days and has a history of an anterior knee wound.
- D. A 7-year-old girl who had a cast on her right ankle is complaining of itching.
Correct answer: A
Rationale: The correct answer is the 8-year-old boy with vomiting, slower movements, and a history of an atrioventricular shunt placement. This report requires immediate attention because the symptoms could indicate a blocked shunt, which is a serious medical condition needing urgent evaluation and intervention. Slower movements in the context of an atrioventricular shunt history could suggest increased intracranial pressure. The other choices involve less urgent issues: choice B describes post-exercise pain, choice C presents with a low-grade fever and headache that could be due to a mild infection, and choice D reports itching associated with a cast, which is a common issue and less critical compared to a potentially blocked shunt.
