An immunocompromised older adult has developed a urinary tract infection and the care team recognizes the need to prevent an exacerbation of the patients infection that could result in urosepsis and septic shock. What action should the nurse perform to reduce the patients risk of septic shock?
- A. Apply an antibiotic ointment to the patients mucous membranes, as ordered.
- B. Perform passive range-of-motion exercises unless contraindicated
- C. Initiate total parenteral nutrition (TPN)
- D. Remove invasive devices as soon as they are no longer needed
Correct Answer: D
Rationale: Early removal of invasive devices can reduce the incidence of infections. Broad application of antibiotic ointments is not performed. TPN may be needed, but this does not directly reduce the risk of further infection. Range-of-motion exercises are not a relevant intervention.

The nurse is caring for a patient who is exhibiting signs and symptoms of hypovolemic shock following injuries suffered in a motor vehicle accident. The nurse anticipates that the physician will promptly order the administration of a crystalloid IV solution to restore intravascular volume. In addition to normal saline, which crystalloid fluid is commonly used to treat hypovolemic shock?
- A. Lactated Ringers
- B. Albumin
- C. Dextran
- D. 3% NaCl
Correct Answer: A
Rationale: Crystalloids are electrolyte solutions used for the treatment of hypovolemic shock. Lactated Ringers and0.9\%$ sodium chloride are isotonic crystalloid fluids commonly used to manage hypovolemic shock. Dextran and albumin are colloids, but Dextran, even as a colloid, is not indicated for the treatment of hypovolemic shock.3\% \mathrm{NaCl}$ is a hypertonic solution and is not isotonic.
The ICU nurse is caring for a patient in neurogenic shock following an overdose of antianxiety medication. When assessing this patient, the nurse should recognize what characteristic of neurogenic shock?
- A. Hypertension
- B. Cool, moist skin
- C. Bradycardia
- D. Signs of sympathetic stimulation
Correct Answer: C
Rationale: In neurogenic shock, the sympathetic system is not able to respond to body stressors. Therefore, the clinical characteristics of neurogenic shock are signs of parasympathetic stimulation. It is characterized by dry, warm skin rather than the cool, moist skin seen in hypovolemic shock. Another characteristic is hypotension with bradycardia, rather than the tachycardia that characterizes other forms of shock.
An adult patient has survived an episode of shock and will be discharged home to finish the recovery phase of his disease process. The home health nurse plays an integral part in monitoring this patient. What aspect of his care should be prioritized by the home health nurse?
- A. Providing supervision to home health aides in providing necessary patient care
- B. Assisting the patient and family to identify and mobilize community resources
- C. Providing ongoing medical care during the familys rehabilitation phase
- D. Reinforcing the importance of continuous assessment with the family
Correct Answer: B
Rationale: The home care nurse reinforces the importance of continuing medical care and helps the patient and family identify and mobilize community resources. The home health nurse is part of a team that provides patient care in the home. The nurse does not directly supervise home health aides. The nurse provides nursing care to both the patient and family, not just the family. The nurse performs continuous and ongoing assessment of the patient; he or she does not just reinforce the importance of that assessment.
A patient is responding poorly to interventions aimed at treating shock and appears to be transitioning to the irreversible stage of shock. What action should the intensive care nurse include during this phase of the patients care?
- A. Communicate clearly and frequently with the patients family.
- B. Taper down interventions slowly when the prognosis worsens.
- C. Transfer the patient to a subacute unit when recovery appears unlikely.
- D. Ask the patients family how they would prefer treatment to proceed.
Correct Answer: A
Rationale: As it becomes obvious that the patient is unlikely to survive, the family must be informed about the prognosis and likely outcome. Opportunities should be provided, throughout the patients care, for the family to see, touch, and talk to the patient. The onus should not be placed on the family to guide care, however. Interventions are not normally reduced gradually when they are deemed ineffective; instead, they are discontinued when they appear futile. The patient would not be transferred to a subacute unit.
A team of nurses are reviewing the similarities and differences between the different classifications of shock. Which subclassifications of circulatory shock should the nurses identify? Select all that apply.
- A. Anaphylactic
- B. Hypovolemic
- C. Cardiogenic
- D. Septic
- E. Neurogenic
Correct Answer: A,D,E
Rationale: The varied mechanisms leading to the initial vasodilation in circulatory shock provide the basis for the further subclassification of shock into three types: septic shock, neurogenic shock, and anaphylactic shock. Hypovolemic and cardiogenic shock are not subclassifications of circulatory shock.
