The nurse is reviewing the lab results of a patient taking lithium for schizoaffective disorder. The lab results show that the blood lithium value is 1.7 mcg/L. What would the nurse take as the priority action?
- A. Induce vomiting
- B. Hold the next dose of Lithium
- C. Administer an antiemetic
- D. Give the next dose of Lithium
Correct Answer: B
Rationale: The correct answer is to hold the next dose of Lithium. The blood lithium value of 1.7 mcg/L exceeds the therapeutic range of 0.5-1.5 mcg/L, indicating potential toxicity. Holding the next dose is crucial to prevent further accumulation of lithium in the bloodstream. Inducing vomiting is not appropriate in this situation as the priority is to prevent further absorption of lithium. Administering an antiemetic is not the priority in lithium toxicity. Giving the next dose of lithium would exacerbate the toxicity and should be avoided.

A patient with Glaucoma is verbalizing his daily medication routine to the nurse. He states he has two different eye drop medications, both every twelve hours. He washes his hands, instills the drops, closes his eyes gently, and presses his finger to the corner of his eye nearest his nose. After waiting 1 minute with his eyes closed, he instills the other medication in the same way. What is the nurse's best response?
- A. You should wait more than 1 minute between different medications.''
- B. Your routine is very good! Can you demonstrate it for me?''
- C. It is actually not the best practice to close your eyes after instilling eye drops.''
- D. You should actually be pressing your finger in the other corner of the eye.''
Correct Answer: A
Rationale: It is recommended to wait 10-15 minutes between different eye drop medications to give them time to absorb and avoid one medication washing another one out. Choice A is the correct response as the patient should wait more than 1 minute between administering different eye drop medications. Choice B is incorrect as the routine described by the patient needs improvement. Choice C is inaccurate as closing the eyes after instilling eye drops is a best practice to ensure proper absorption. Choice D is incorrect as pressing the finger to the corner of the eye nearest the nose is the correct technique.
A client is admitted for a head injury. His body is lying in an abnormal position and the physician states he is exhibiting decorticate posturing. Based on this assessment, the nurse can expect to find the client with:
- A. The legs extended and rotated internally; the elbow, wrists, and fingers flexed
- B. The legs pulled toward the chest; the head bent back at a 30-degree angle
- C. The back arched; the arms and legs extended and rigid
- D. The legs extended and rotated externally; the head turned to the right or the left
Correct Answer: A
Rationale: Decorticate posturing is indicative of an injury to the corticospinal tract, resulting in abnormal posturing. It may occur spontaneously or in response to stimulation. This posture involves the legs being extended and rotated internally, while the elbows, wrists, and fingers are flexed inward. Choice A is correct because it accurately describes the expected positioning associated with decorticate posturing. Choices B, C, and D are incorrect. Choice B describes a different type of posturing known as opisthotonos. Choice C describes an exaggerated arching of the back, which is not characteristic of decorticate posturing. Choice D describes a different type of posturing with external rotation of the legs and head turning to the side, not consistent with decorticate posturing.
The nurse is caring for a 7-year-old child with glomerulonephritis and is preparing to discuss the plan of care with the parents. In anticipating this encounter, the nurse recognizes that which is a common reaction of parents to the diagnosis of glomerulonephritis?
- A. Fear of the complicated treatment regimen
- B. Anger at the child for requiring hospitalization
- C. Guilt that they did not seek treatment more quickly
- D. Depression that the child may not be able to play sports
Correct Answer: C
Rationale: Guilt is a common reaction of parents when their child is diagnosed with glomerulonephritis. Parents often blame themselves for not responding promptly to the child's initial symptoms or feel guilty for not seeking treatment sooner, thinking they could have prevented the development of glomerular damage. While fear of a complicated treatment regimen, anger at the child for hospitalization, and depression about the child not playing sports may be valid concerns, they are generally not as commonly observed as the feeling of guilt among parents in this situation.
The nurse is caring for an infant with cryptorchidism. The nurse anticipates that the most likely diagnostic study to be prescribed would be the one that assesses which item?
- A. Babinski reflex
- B. DNA synthesis
- C. Urinary function
- D. Chromosomal analysis
Correct Answer: C
Rationale: Cryptorchidism, also known as undescended testes, may be caused by hormonal deficiency, intrinsic testicular abnormality, or a structural problem. Diagnostic studies for cryptorchidism typically involve assessing urinary function because the kidneys and testes originate from the same embryonic tissue. The Babinski reflex is a test for neurological function and is not relevant to evaluating cryptorchidism. DNA synthesis and chromosomal analysis are not commonly used diagnostic tests for cryptorchidism, as they are unrelated to the disorder's etiology or presentation.
Mr. C is brought to the hospital with severe burns over 45% of his body. His heart rate is 124 bpm and thready, BP 84/46, respirations 24/minute and shallow. He is apprehensive and restless. Which of the following types of shock is Mr. C at highest risk for?
- A. Septic shock
- B. Hypovolemic shock
- C. Neurogenic shock
- D. Cardiogenic shock
Correct Answer: B
Rationale: Mr. C, who has severe burns over 45% of his body, is at highest risk for hypovolemic shock. Burns lead to a loss of plasma volume, reducing the circulating fluid volume and impairing perfusion to vital organs and extremities. In this scenario, the signs of shock, such as increased heart rate, low blood pressure, shallow respirations, and restlessness, indicate a state of hypovolemic shock due to significant fluid loss. Septic shock (choice A) is primarily caused by severe infections, neurogenic shock (choice C) results from spinal cord injuries, and cardiogenic shock (choice D) stems from heart failure. However, in this case, the presentation aligns most closely with hypovolemic shock due to the extensive burn injury and its effects on fluid volume and perfusion.
