A patient at high risk for pulmonary embolism is receiving enoxaparin. The nurse should provide the patient with what explanation?
- A. “I’m going to contact the pharmacist to see if you can take this medication by mouth.”
- B. “This injection is being given to prevent blood clots fr om forming.”
- C. “This medication will dissolve any blood clots you migabhirtb .gcoemt./”te st
- D. “I will contact your primary care provide to discuss wh y you are getting this medication.” t
Correct Answer: B
Rationale: The correct answer is B: “This injection is being given to prevent blood clots from forming.” Enoxaparin is an anticoagulant used to prevent blood clots. It is administered through injection, not orally (A). Enoxaparin does not dissolve existing blood clots (C). Contacting the primary care provider to discuss the medication is not necessary in this scenario (D). The correct choice emphasizes the purpose of enoxaparin in preventing new blood clots.

As part of the admission process, the nurse asks several questions about family relationships. The nurse bases these actions on which rationale?
- A. Assessing family relationships is an initial step in including the family in patient care.
- B. These questions are part of the admission assessment tool required by this CCU.
- C. The nurse has a natural curiosity and wishes to know how the family members relate for her own knowledge.
- D. There is an ongoing research study to identify variant family patterns related to disease incidence.
Correct Answer: A
Rationale: Step-by-step rationale for why choice A is correct:
1. Involving the family in patient care is crucial for holistic care.
2. Assessing family relationships helps identify support systems and potential conflicts.
3. Understanding family dynamics aids in creating a comprehensive care plan.
4. Family involvement can enhance patient outcomes and satisfaction.
Summary of incorrect choices:
B. Irrelevant, as the focus is on patient-centered care, not just fulfilling an assessment tool.
C. Personal curiosity is not a valid reason for assessing family relationships in healthcare.
D. Conducting research on family patterns does not directly impact the immediate care of the patient.
Family assessment is essential in order to meet family nee ds. Which of the following must be assessed first to assist the nurse in providing family-centered care?
- A. Assessment of patient and family’s developmental stag es and needs
- B. Description of the patient’s home environment
- C. Identification of immediate family, extended family, a nd decision makers
- D. Observation and assessment of how family members fu nction with each other
Correct Answer: A
Rationale: The correct answer is A because assessing the patient and family's developmental stages and needs is crucial in understanding their current situation and determining the appropriate care plan. By assessing developmental stages, the nurse can tailor interventions to meet the family's specific needs. This assessment also helps in identifying potential challenges or areas requiring support.
Choice B is incorrect as it focuses solely on the physical environment and does not address the family's developmental stages and needs.
Choice C is incorrect as it emphasizes identifying family members without considering the importance of understanding their developmental stages and needs in providing family-centered care.
Choice D is incorrect as it concentrates on family dynamics without directly addressing the crucial aspect of assessing developmental stages and needs for effective family-centered care.
What are the diagnostic criteria for acute respiratory distress syndrome (ARDS)? (Select all that apply.)
- A. Bilateral infiltrates on chest x-ray study
- B. Decreased cardiac output
- C. PaO /FiO ratio of less than 200 2 2
- D. Pulmonary artery occlusion pressure (PAOP) of more than 18 mm Hg
Correct Answer: A
Rationale: The correct answer is A: Bilateral infiltrates on chest x-ray study. ARDS diagnosis requires bilateral infiltrates on chest x-ray, indicative of non-cardiogenic pulmonary edema. Choice B, decreased cardiac output, is not a diagnostic criterion for ARDS. Choice C, PaO2/FiO2 ratio of less than 200, is a key diagnostic criteria for ARDS, indicating severe hypoxemia. Choice D, PAOP of more than 18 mm Hg, is used to differentiate between cardiogenic and non-cardiogenic causes of pulmonary edema, but it is not a direct diagnostic criterion for ARDS.
A PaCO 2 of 48 mm Hg is associated with what outcome?
- A. Hyperventilation
- B. Hypoventilation
- C. Increased absorption of O
- D. Increased excretion of HCO
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation. A PaCO2 of 48 mm Hg indicates an elevated level of carbon dioxide in the blood, which is typically seen in hypoventilation where the lungs are not effectively removing CO2. Hypoventilation leads to respiratory acidosis. Option A is incorrect because hyperventilation would decrease PaCO2 levels. Option C is incorrect as it does not directly relate to PaCO2 levels. Option D is incorrect as increased excretion of HCO3- would not directly affect PaCO2 levels.
The nurse is caring for a patient who has undergone major abdominal surgery. The nurse notices that the patient’s urine output has been less than 20 mL/hour for the past 2 hours. The patient’s blood pressure is 100/60 mm Hg, and the pulse is 110 beats/min. Previously, the pulse was 90 beats/min with a blood pressure of 120/80 mm Hg. The nurse should
- A. contact the provider and expect a prescription for a normal saline bolus.
- B. wait until the provider makes rounds to report the assessment findings.
- C. continue to evaluate urine output for 2 more hours.
- D. ignore the urine output, as this is most likely postrenal in origin.
Correct Answer: A
Rationale: The correct answer is A: contact the provider and expect a prescription for a normal saline bolus. The patient is showing signs of hypovolemia with decreased urine output, low blood pressure, and elevated heart rate. This indicates inadequate perfusion and potential hypovolemic shock. Administering a normal saline bolus will help restore intravascular volume and improve perfusion. Waiting for the provider to make rounds (option B) could delay necessary intervention. Continuing to evaluate urine output for 2 more hours (option C) is not appropriate given the patient's current condition. Ignoring the urine output (option D) is dangerous as it could lead to further complications.
