A nurse is caring for a client who has hemophilia A and is about to begin taking desmopressin to prevent bleeding. The nurse should monitor the client for which of the following adverse reactions?
- A. Weight loss
- B. Edema
- C. Polyuria
- D. Bradycardia
Correct Answer: B
Rationale: The correct answer is B: Edema. Desmopressin is a medication that can cause fluid retention, leading to edema. Hemophilia A clients are at risk for bleeding, so desmopressin is given to improve clotting. Weight loss (A), polyuria (C), and bradycardia (D) are not common adverse reactions of desmopressin. Weight loss and polyuria are more associated with diabetes insipidus, a condition that desmopressin is used to treat. Bradycardia is not a typical adverse reaction of desmopressin.

A hospitalized client has a platelet count of 58,000/mm³. What action by the nurse is best?
- A. Encourage high-protein foods.
- B. Institute neutropenic precautions.
- C. Limit visitors to healthy adults.
- D. Place the client on safety precautions.
Correct Answer: D
Rationale: The correct answer is D: Place the client on safety precautions. A platelet count of 58,000/mm³ indicates thrombocytopenia, increasing the risk of bleeding. Safety precautions aim to prevent injury and minimize bleeding risks. Encouraging high-protein foods (choice A) is not directly related to managing thrombocytopenia. Instituting neutropenic precautions (choice B) is for clients with low white blood cell counts, not platelet counts. Limiting visitors to healthy adults (choice C) is important for infection control, not specifically for thrombocytopenia. In summary, placing the client on safety precautions is the best action to prevent bleeding complications.
The nurse is staying with a patient who has been started on a blood transfusion. Which assessment should the nurse perform during a blood product infusion to detect a reaction?
- A. Vital signs
- B. Skin turgor
- C. Bowel sounds
- D. Pupil reactivity
Correct Answer: A
Rationale: The correct answer is A: Vital signs. During a blood transfusion, the nurse should monitor the patient's vital signs regularly to detect any signs of a transfusion reaction, such as fever, chills, rash, or hypotension. Vital signs provide crucial information about the patient's overall condition and can help the nurse identify and respond promptly to any adverse reactions. Skin turgor (B), bowel sounds (C), and pupil reactivity (D) are not directly related to monitoring for transfusion reactions and are not sensitive indicators of an adverse reaction during a blood transfusion. Monitoring vital signs is essential for patient safety and early detection of any complications during the transfusion process.
An older client asks the nurse why 'people my age' have weaker immune systems than younger people. What responses by the nurse are best? (Select all that apply.)
- A. Bone marrow produces more blood cells as you age.'
- B. You may have decreased levels of circulating platelets.'
- C. You have lower levels of plasma proteins in the blood.'
- D. Lymphocytes become more reactive to antigens.'
Correct Answer: C
Rationale: The correct answer is C: 'You have lower levels of plasma proteins in the blood.' As we age, there is a decline in the production of plasma proteins, which play a crucial role in immune function. These proteins help fight infections and regulate immune responses. Lower levels can weaken the immune system's ability to respond effectively to pathogens.
Choice A is incorrect because while bone marrow does produce blood cells, it does not directly relate to the weakening of the immune system with age. Choice B is incorrect as decreased platelet levels primarily affect blood clotting, not immune function. Choice D is incorrect because lymphocytes becoming more reactive to antigens is not a characteristic of aging immune systems.
In iron deficiency anemia there is characteristically
- A. An atrophic gastritis
- B. A low mean corpuscular volume
- C. A reduced total iron binding capacity
- D. Megaloblastic changes in the bone marrow
Correct Answer: B
Rationale: Step-by-step rationale:
1. Iron deficiency leads to decreased hemoglobin synthesis, resulting in smaller red blood cells.
2. Mean corpuscular volume (MCV) measures the average size of red blood cells.
3. In iron deficiency anemia, MCV is low due to the smaller red blood cells.
4. Therefore, choice B is correct as it reflects the characteristic feature of iron deficiency anemia.
Summary:
A: Atrophic gastritis is seen in pernicious anemia, not iron deficiency anemia.
C: Total iron binding capacity is increased, not reduced, in iron deficiency anemia.
D: Megaloblastic changes in the bone marrow are seen in megaloblastic anemias, not iron deficiency anemia.
You receive a phone call from a community pediatrician who is caring for a 2-year-old toddler with a cancer predisposition syndrome. The pediatrician describes a child at the 95th percentile for height and weight with a history of corrective oral surgery to reduce a large tongue and a history of an omphalocele in infancy. The pediatrician is currently performing ultrasound of the abdomen and laboratory evaluation for this patient every 3 months. Which tumor is this patient most at risk of developing?
- A. Pleuropulmonary blastoma
- B. Hepatocellular carcinoma
- C. Cystic nephroma
- D. Nephroblastoma
Correct Answer: D
Rationale: The correct answer is D: Nephroblastoma (Wilms tumor). This patient likely has Beckwith-Wiedemann syndrome given the features of overgrowth, macroglossia, and omphalocele. Beckwith-Wiedemann syndrome is associated with an increased risk of Wilms tumor. Wilms tumor is the most common renal malignancy in childhood. Monitoring for Wilms tumor with ultrasound and laboratory evaluations is appropriate due to the increased risk in this patient population.
Choice A: Pleuropulmonary blastoma is a rare lung tumor more commonly seen in children under 2 years old. It is not typically associated with Beckwith-Wiedemann syndrome.
Choice B: Hepatocellular carcinoma is a primary liver cancer more commonly seen in adults, not children with Beckwith-Wiedemann syndrome.
Choice C: Cystic nephroma is a benign kidney tumor typically seen in young children, but it is not associated with Beckwith-Wiedemann syndrome nor is it malignant
