In response to chronic hypoxia, which physiological adaptation occurs in the body to increase oxygen delivery to tissues?
- A. Decreased erythropoietin production
- B. Decreased red blood cell production
- C. Increased cardiac output
- D. Decreased ventilation rate
Correct Answer: C
Rationale: In response to chronic hypoxia, the body adapts to increase oxygen delivery to tissues by increasing cardiac output. This is achieved by increasing the heart rate and stroke volume, allowing more oxygenated blood to be pumped to the tissues. The increased cardiac output helps compensate for the lower oxygen levels in the blood, ensuring that tissues receive an adequate supply of oxygen despite the hypoxic conditions. This physiological adaptation is essential for maintaining tissue oxygenation and supporting overall cellular function in the presence of chronic hypoxia.

A patient presents with recurrent episodes of epistaxis, gum bleeding, and easy bruising. Laboratory tests reveal prolonged bleeding time, normal platelet count, and normal PT and aPTT. Which of the following conditions is most likely to cause these findings?
- A. Von Willebrand disease
- B. Glanzmann thrombasthenia
- C. Hemophilia A
- D. Bernard-Soulier syndrome
Correct Answer: A
Rationale: The clinical presentation of recurrent episodes of epistaxis, gum bleeding, and easy bruising, along with laboratory findings of prolonged bleeding time, normal platelet count, and normal coagulation studies (PT and aPTT) are highly suggestive of Von Willebrand disease. Von Willebrand disease is the most common inherited bleeding disorder and is characterized by a deficiency or dysfunction of von Willebrand factor (vWF), which plays a key role in platelet adhesion and aggregation. The prolonged bleeding time is due to impaired platelet adhesion to the damaged vessel wall in the absence of functional vWF. Normal platelet count and normal PT/aPTT help differentiate Von Willebrand disease from other bleeding disorders such as hemophilia and platelet function disorders like Glanzmann thrombasthenia and Bernard-Soulier syndrome.
A woman in active labor experiences frequent and intense uterine contractions with minimal rest intervals, leading to maternal fatigue and decreased fetal oxygenation. What maternal condition should the nurse assess for that may contribute to this abnormal labor pattern?
- A. Maternal dehydration
- B. Uterine hyperstimulation
- C. Pelvic outlet obstruction
- D. Maternal exhaustion
Correct Answer: B
Rationale: Uterine hyperstimulation is a condition in which the uterus contracts too frequently or too intensely, leading to decreased blood flow and oxygenation to the placenta. This can result in maternal fatigue and decreased fetal oxygenation due to the lack of sufficient rest intervals between contractions. Uterine hyperstimulation can be caused by factors such as the use of synthetic oxytocin (Pitocin) to induce or augment labor, uterine abnormalities, or maternal conditions like pre-eclampsia. It is important for the nurse to assess for uterine hyperstimulation in a woman experiencing frequent and intense contractions to intervene promptly and prevent adverse outcomes for both the mother and the baby.
In instilling the eye drops you have to tilt the back slightly Claudia's head. Which of the following is the RATIONALE for this nursing action?
- A. To prevent any spill from the eye during the procedure
- B. To keep any debris away from the lacrimal duct
- C. To facilitate the procedure
- D. To reach the conjunctival sac easily
Correct Answer: D
Rationale: Tipping Claudia's head back slightly helps in reaching the conjunctival sac easily. The conjunctival sac is a small space between the lower eyelid and the eye itself where eye drops are typically administered. Tilting the head back allows for better access to this area, ensuring the eye drops are delivered accurately and effectively into the eye.
Right after endorsement and during the rounds, the incoming nurse observes that the IV fluid is at 800 cc level and not 400cc, as endorsed. What is the CORRECT information that she will chart?
- A. Anything goes, nobody reads the charting anyway.
- B. Record the 400 cc.
- C. Chart that she received 800
- D. Refer to the Head Nurse on what to do.
Correct Answer: C
Rationale: The correct information that the incoming nurse should chart is that she received 800 cc of IV fluid. It is crucial for the charting to accurately reflect the actual situation to provide an accurate record for the patient's care. In this scenario, the discrepancy between the endorsed amount (400 cc) and the observed amount (800 cc) should be documented to ensure transparency and continuity of care. This deviation from the expected amount should be clearly recorded for proper monitoring and evaluation of the patient's condition.
Which of the following charting rules will keep the nurse legally safe? I. Documenting worries and all concerns as verbalized by the patient. II Charting at the end of the shift only. III.Discussing of recorded cases and diagnosis of the patient. IV. Recording all information verbalized by patient and family.
- A. III, IV
- B. I
- C. I, III
- D. II
Correct Answer: B
Rationale: The correct charting rule to keep the nurse legally safe is to document worries and all concerns as verbalized by the patient (Choice I). This is important for accurately reflecting the patient's condition, communication, and potential interventions. Charting at the end of the shift only (Choice II) is not recommended as it can lead to missed important details or delayed documentation. Discussing recorded cases and diagnoses of the patient (Choice III) breaches patient confidentiality and violates HIPAA laws. Recording all information verbalized by the patient and family (Choice IV) may include unnecessary details and could potentially lead to misinterpretation or misunderstanding, which might not be legally advantageous.
