A client diagnosed with DIC is ordered heparin. What is the reason for this medication?
- A. Prevent clot formation
- B. Increase clot formation
- C. Increased blood flow to target organs
- D. Decrease blood flow to target organs
Correct Answer: A
Rationale: The correct answer is A: Prevent clot formation. Heparin is an anticoagulant that inhibits the formation of blood clots. In DIC (Disseminated Intravascular Coagulation), there is excessive clotting throughout the body, leading to organ damage. By administering heparin, we aim to prevent further clot formation and reduce the risk of complications.
Choice B is incorrect because heparin does not increase clot formation; it works to inhibit clotting. Choice C is incorrect as heparin does not directly increase blood flow to target organs. Choice D is also incorrect as heparin does not decrease blood flow to target organs; its primary role is anticoagulation.

The nurse is gathering data on a patient. Which data will the nurse report as objective data?
- A. States “doesn’t feel good”
- B. Reports a headache
- C. Respirations 16
- D. Nauseated
Correct Answer: C
Rationale: The correct answer is C because respiratory rate is an observable and measurable data point, making it objective. Objective data is factual and observable, such as vital signs. Choices A, B, and D are subjective data as they rely on the patient's perception or interpretation, which can be influenced by various factors and may not always be accurate or reliable. In this case, the nurse can directly measure and document the patient's respiratory rate, making it an objective piece of information.
A client with a nagging cough makes an appointment to see the physician after reading that this symptom is one of the seven warning signs of cancer. What is another warning sign of cancer?
- A. Persistent nausea
- B. Indigestion
- C. Rash
- D. Chronic ache or pain
Correct Answer: D
Rationale: The correct answer is D: Chronic ache or pain. Persistent cough and chronic ache or pain are both common warning signs of cancer. Chronic pain can be a symptom of various types of cancer, signaling the presence of a tumor or cancerous growth. It is important for the client to seek medical evaluation to rule out any underlying serious condition.
A: Persistent nausea is not typically considered a common warning sign of cancer. While it can be a symptom in certain types of cancer or due to treatment side effects, it is not as prominent as chronic ache or pain.
B: Indigestion is a common symptom that can be caused by various non-cancer-related issues such as dietary habits, stress, or gastrointestinal disorders. It is not typically considered a direct warning sign of cancer.
C: Rash is generally not a common warning sign of cancer. Rashes are more commonly associated with skin conditions, allergic reactions, or infections rather than being an indicator of cancer.
The patient is dangling at the bedside and states, “Oh, my stomach is tearing open.” Which of the following actions should the nurse immediately take when dehiscence occurs?
- A. Have patient sit upright in a chair.
- B. Have patient lie down.
- C. Slow IV fluids.
- D. Obtain a sterile suture set.
Correct Answer: B
Rationale: The correct answer is B: Have patient lie down. When a patient experiences dehiscence (surgical wound separation), lying down helps reduce tension on the wound, minimizing the risk of further tearing. This position also allows the nurse to assess the wound properly. Choice A is incorrect because sitting upright can increase intra-abdominal pressure, worsening the dehiscence. Choice C is incorrect as slowing IV fluids is not a priority in managing dehiscence. Choice D is incorrect because obtaining a sterile suture set should only be done by a healthcare provider and is not the immediate action needed for dehiscence.
Following hypophysectomy, patients require extensive teaching regarding this major alteration in their lifestyle
- A. Abnormal distribution of body hair
- B. Lifetime dependency on hormone replacement
- C. The need to drink many fluids to replace those lost
- D. The need to undergo repeat surgical procedures
Correct Answer: B
Rationale: The correct answer is B (Lifetime dependency on hormone replacement) because after hypophysectomy (removal of the pituitary gland), patients will no longer produce essential hormones like growth hormone, thyroid-stimulating hormone, etc. Therefore, they will require lifelong hormone replacement therapy to maintain normal bodily functions.
A: Abnormal distribution of body hair is not directly related to hypophysectomy.
C: While fluid intake may be important post-surgery, it is not the primary focus of teaching.
D: There is typically no need for repeat surgical procedures after a hypophysectomy, as it is a one-time surgery to address specific issues.
In summary, choice B is correct as it directly addresses the long-term implications of the surgery on hormone production and the need for replacement therapy, while the other choices are not directly relevant to the post-operative care of hypophysectomy patients.
Nurse Raymond is handling a group of student nurses and he is teaching them about fluids and electrolytes. He is correct when he says that a substance moves from an area of higher concentration, this is:
- A. osmosis
- B. filtration
- C. diffusion
- D. active transport
Correct Answer: C
Rationale: Correct Answer: C - Diffusion
Rationale: Diffusion is the movement of a substance from an area of higher concentration to an area of lower concentration. This process occurs naturally to achieve equilibrium. In the context of fluids and electrolytes, this movement helps maintain balance within the body. Unlike osmosis, which involves the movement of water molecules across a semi-permeable membrane, diffusion applies to the movement of all types of substances. Filtration involves the movement of substances through a barrier under pressure, and active transport requires energy to move substances against a concentration gradient. Therefore, the correct answer is diffusion as it aligns with the principle of movement from high to low concentration for achieving equilibrium.
