Nokea
The nurse reviews the laboratory test results of a patient admitted with abdominal pain. Which information will be most important for the nurse to communicate to the health care provider?
- A. Monocytes 4%
- B. Hemoglobin 13.6 g/dL
- C. Platelet count 168,000/μL
- D. White blood cell (WBC) count 15,500/μL
Correct Answer: A
Rationale: The correct answer is A. A low percentage of monocytes can indicate a viral infection. This is crucial information to communicate as it suggests a specific type of infection that may require targeted treatment. Choices B, C, and D do not directly relate to an infectious process and are within normal ranges, so they are not as urgent to communicate to the healthcare provider in this context.

A patient in the emergency department complains of back pain and difficulty breathing 15 minutes after a transfusion of packed red blood cells is started. The nurse's first action should be to
- A. administer oxygen therapy at a high flow rate
- B. obtain a urine specimen to send to the laboratory
- C. notify the healthcare provider about the symptoms
- D. disconnect the transfusion and infuse normal saline
Correct Answer: D
Rationale: The patient's symptoms, back pain, and difficulty breathing after the transfusion indicate a possible acute hemolytic reaction, a severe transfusion reaction. The priority action in this situation is to discontinue the transfusion immediately to prevent further complications. Infusing normal saline helps maintain the patient's intravascular volume and prevent renal damage. Administering oxygen or obtaining a urine specimen is not the most urgent action and could delay essential treatment. Notifying the healthcare provider is important but should come after ensuring the patient's safety by stopping the blood transfusion.
Several patients call the outpatient clinic and ask to make an appointment as soon as possible. Which patient should the nurse schedule to be seen first?
- A. A 44-year-old with sickle cell anemia who reports his eyes always look somewhat yellow
- B. A 23-year-old with no previous health problems who has a nontender lump in the axilla
- C. A 50-year-old with early-stage chronic lymphocytic leukemia who reports chronic fatigue
- D. A 19-year-old with hemophilia who wants to learn to self-administer factor VII replacement
Correct Answer: B
Rationale: The patient's young age and the presence of a nontender lump in the axilla raise concerns for possible lymphoma, which requires prompt evaluation and treatment. This patient should be seen first to rule out any serious underlying condition. Choice A is less urgent as yellowish eyes in sickle cell anemia may be due to jaundice but not necessarily an acute issue. Choice C, a 50-year-old with chronic fatigue related to early-stage chronic lymphocytic leukemia, is a known condition that can be managed on a routine basis. Choice D, a 19-year-old with hemophilia wanting to self-administer factor VII replacement, is important but less urgent compared to the potential lymphoma presentation in choice B.
A patient who is receiving methotrexate for severe rheumatoid arthritis develops a megaloblastic anemia. The nurse will anticipate teaching the patient about increasing oral intake of
- A. iron.
- B. folic acid.
- C. cobalamin (vitamin B12).
- D. ascorbic acid (vitamin C).
Correct Answer: C
Rationale: The correct answer is C: cobalamin (vitamin B12). Methotrexate can lead to a deficiency in cobalamin, resulting in megaloblastic anemia. Therefore, increasing the oral intake of cobalamin is essential to address this deficiency. Choice A, iron, is incorrect because megaloblastic anemia caused by methotrexate is not typically due to iron deficiency. Choice B, folic acid, is also incorrect as methotrexate does not directly cause folic acid deficiency. Choice D, ascorbic acid (vitamin C), is incorrect as it is not directly related to megaloblastic anemia caused by methotrexate; instead, cobalamin is the key vitamin that needs attention.
A patient with pancytopenia of unknown origin is scheduled for the following diagnostic tests. The nurse will provide a consent form to sign for which test?
- A. Bone marrow biopsy
- B. Abdominal ultrasound
- C. Complete blood count (CBC)
- D. Activated partial thromboplastin time (aPTT)
Correct Answer: A
Rationale: In the case of a patient with pancytopenia of unknown origin, a bone marrow biopsy is usually indicated to determine the cause. A bone marrow biopsy is a minor surgical procedure that requires the patient or guardian to sign a surgical consent form. Abdominal ultrasound (Choice B) is not typically used to diagnose pancytopenia. A Complete Blood Count (CBC) (Choice C) is a routine blood test and does not require a specific consent form. Activated Partial Thromboplastin Time (aPTT) (Choice D) is a coagulation test and not typically performed to diagnose pancytopenia.
The nurse assesses a patient who has numerous petechiae on both arms. Which question should the nurse ask the patient?
- A. Are you taking any oral contraceptives?
- B. Have you been prescribed antiseizure drugs?
- C. Do you take medication containing salicylates?
- D. How long have you been taking antihypertensive drugs?
Correct Answer: C
Rationale: The correct answer is C: 'Do you take medication containing salicylates?' Petechiae are tiny, pinpoint, red or purple spots on the skin due to bleeding under the skin. Salicylates, which are found in medications like aspirin, interfere with platelet function and can lead to petechiae and ecchymoses. Asking about salicylate-containing medications is crucial in this situation. Choices A, B, and D are incorrect because they are not directly related to the development of petechiae.
