1. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. Bleeding time
- D. Platelet count
Correct answer: B
Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.
2. A client who is acutely ill has vigilant oral care included in their plan of care. What factor increases this client's risk for dental caries?
- A. Hormonal changes induced by the stress response leading to an acidic oral environment
- B. Systemic infections commonly affecting the teeth
- C. Intravenous hydration lacking fluoride
- D. Inadequate nutrition and reduced saliva production contributing to cavities
Correct answer: D
Rationale: Inadequate nutrition and decreased saliva production can lead to a conducive environment for the development of dental caries. Without proper nutrition and sufficient saliva, the protective mechanisms against cavities are compromised, making the individual more susceptible to tooth decay.
3. After performing a paracentesis on a client with ascites, 3 liters of fluid are removed. Which assessment parameter is most critical for the nurse to monitor following the procedure?
- A. Pedal pulses.
- B. Breath sounds.
- C. Gag reflex.
- D. Vital signs.
Correct answer: D
Rationale: Following a paracentesis where a significant amount of fluid is removed, it is crucial to monitor the client's vital signs. This helps in detecting any signs of hypovolemia, such as changes in blood pressure, heart rate, and respiratory rate, which could indicate complications post-procedure. Monitoring the vital signs allows for prompt intervention if there are any deviations from the baseline values.
4. A 75-year-old patient is admitted for pancreatitis. Which tool would be the most appropriate for the nurse to use during the admission assessment?
- A. Drug Abuse Screening Test (DAST-10)
- B. Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar)
- C. Screening Test-Geriatric Version (SMAST-G)
- D. Mini-Mental State Examination
Correct answer: C
Rationale: The most appropriate tool for the nurse to use during the admission assessment of a 75-year-old patient admitted for pancreatitis is the Screening Test-Geriatric Version (SMAST-G). Since alcohol abuse is a common factor associated with pancreatitis, screening for alcohol use is crucial. The SMAST-G is a validated short-form alcoholism screening instrument tailored for older adults. If the patient screens positively on the SMAST-G, then the CIWA-Ar would be useful for further assessment. The Drug Abuse Screening Test (DAST-10) provides information on substance use in general, not specific to alcohol. The Mini-Mental State Examination is used to assess cognitive function, not alcohol abuse.
5. A 38-year-old male client collapsed at his outside construction job in Texas in July. His admitting vital signs to ICU are, BP 82/70, heart rate 140 beats/minute, urine output 10 ml/hr, skin cool to the touch. Pulmonary artery (PA) pressures are, PAWP 1, PAP 8/2, RAP -1, SVR 1600. What nursing action has the highest priority?
- A. Apply a hypothermia unit to stabilize core temperature.
- B. Increase the client's IV fluid rate to 200 ml/hr.
- C. Call the hospital chaplain to counsel the family.
- D. Draw blood cultures x3 to detect infection.
Correct answer: B
Rationale: The correct answer is to increase the client's IV fluid rate to 200 ml/hr. The client's vital signs indicate signs of shock and hypovolemia, making fluid resuscitation the priority to address these conditions. Improving intravascular volume is crucial to stabilize the client's blood pressure, heart rate, and urine output, ultimately improving organ perfusion and addressing the underlying issue of hypovolemia.
