A laboratory finding of granulocytosis
- A. Complete absence of peripheral blood granulocytes and their precursors in the bone marrow
- B. Acute bacterial infections
- C. Myeloproliferative disorders
- D. Increased numbers of granulocytes in blood and bone marrow
Correct Answer: D
Rationale: The correct answer is D because granulocytosis refers to an increase in granulocytes in both blood and bone marrow. This finding is commonly seen in conditions such as infections and inflammatory processes. The other choices are incorrect because A describes agranulocytosis, B is a potential cause of granulocytosis, and C typically involves abnormal proliferation of myeloid cells rather than just granulocytes.

A nurse is monitoring a client following ferrous sulfate administration. The nurse should monitor the client for which of the following adverse effects?
- A. Phlebitis
- B. Dark
- C. orange-colored stools
- D. Constipation
Correct Answer: D
Rationale: The correct answer is D: Constipation. Ferrous sulfate, an iron supplement, commonly causes constipation due to its effects on the digestive system. Iron slows down bowel movements, leading to constipation. Monitoring for constipation is crucial to ensure the client's comfort and prevent complications.
Phlebitis (choice A) is not a common adverse effect of ferrous sulfate administration. Dark, tarry stools (choice B) can indicate gastrointestinal bleeding but are not directly related to iron supplementation. Orange-colored stools (choice C) are not a typical side effect of ferrous sulfate and are more commonly associated with certain foods or medications.
Half life of plat. Is:
- A. 1-2days
- B. 3-4days
- C. 5-6days
- D. 7-8days
Correct Answer: B
Rationale: The correct answer is B (3-4 days) because the half-life of platinum is known to be around 3-4 days based on scientific research and studies. This means that within this time frame, half of the amount of platinum will decay or disintegrate. The other choices (A, C, D) are incorrect because they do not align with the established half-life value of platinum. Option A (1-2 days), C (5-6 days), and D (7-8 days) do not fall within the typical range of platinum's half-life duration as determined by scientific data and experimentation. Therefore, option B is the most accurate and scientifically supported choice for the half-life of platinum.
Koilonychias is a specific feature of
- A. Hemolytic anemia
- B. Sickle cell disease
- C. Thalassemia major
- D. Iron deficiency anemia
Correct Answer: D
Rationale: Step-by-step rationale for why D is correct:
1. Koilonychias is characterized by spoon-shaped nails, a common symptom of iron deficiency anemia due to decreased hemoglobin levels.
2. Iron is essential for normal nail growth, and its deficiency can lead to changes in nail shape.
3. Hemolytic anemia (A) is characterized by the premature destruction of red blood cells, not typically associated with koilonychias.
4. Sickle cell disease (B) causes abnormal hemoglobin, leading to sickle-shaped red blood cells, not related to koilonychias.
5. Thalassemia major (C) is a genetic disorder affecting hemoglobin production, but it does not directly cause koilonychias.
The nurse examines the lymph nodes of a patient during a physical assessment. Which assessment finding would be of most concern to the nurse?
- A. A 2-cm nontender supraclavicular node
- B. A 1-cm mobile and nontender axillary node
- C. An inability to palpate any superficial lymph nodes
- D. Firm inguinal nodes in a patient with an infected foot
Correct Answer: A
Rationale: The correct answer is A. A 2-cm nontender supraclavicular node is of most concern as supraclavicular nodes are not normally palpable, and their enlargement can indicate underlying malignancy, such as metastatic cancer.
B: A 1-cm mobile and nontender axillary node is within normal limits.
C: Inability to palpate superficial lymph nodes may be due to factors like obesity or normal variation.
D: Firm inguinal nodes in a patient with an infected foot are expected as a local response to infection.
Half life of plat. Is:
- A. 1-2days
- B. 3-4days
- C. 5-6days
- D. 7-8days
Correct Answer: B
Rationale: The correct answer is B: 3-4 days. The half-life of a substance is the time it takes for half of the original amount to decay. In this case, since the half-life of platinum is 3-4 days, it means that after 3-4 days, half of the initial amount of platinum will have decayed. This answer is correct because it accurately represents the time frame for platinum decay. The other choices are incorrect because they do not correspond to the known half-life of platinum. Choice A (1-2 days), C (5-6 days), and D (7-8 days) are outside the typical half-life range for platinum, making them incorrect options.
