1. When instructing a client with a new prescription for Timolol on how to insert eye drops, which area should the nurse instruct the client to press on to prevent systemic absorption of the medication?
- A. Bony orbit
- B. Nasolacrimal duct
- C. Conjunctival sac
- D. Outer canthus
Correct answer: B
Rationale: Pressing on the nasolacrimal duct, located near the inner corner of the eye, blocks the lacrimal punctum and prevents the medication from entering the systemic circulation. This technique helps to ensure the medication stays localized in the eye, enhancing its therapeutic effect while minimizing systemic side effects. Choices A, C, and D are incorrect. The bony orbit is the eye socket and not a site to press for preventing systemic absorption. The conjunctival sac is where eye drops are instilled, not pressed on. The outer canthus is also not the correct area to press to prevent systemic absorption.
2. A client with renal failure and an elevated phosphorus level is prescribed aluminum hydroxide 300 mg PO three times daily. For which of the following adverse effects should the nurse inform the client?
- A. Constipation
- B. Metallic taste
- C. Headache
- D. Muscle spasms
Correct answer: A
Rationale: Correct. Aluminum hydroxide is known to cause constipation as a common side effect. Instructing the client about this potential adverse effect is important for their awareness and management. The other options, metallic taste, headache, and muscle spasms, are not typically associated with aluminum hydroxide use. Therefore, the nurse should focus on educating the client about the increased risk of constipation and provide guidance on managing this side effect to improve the client's comfort and treatment adherence.
3. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?
- A. Use an electric shaver to remove excess hair on the extremity.
- B. Select the antecubital area to insert the IV catheter.
- C. Distend the veins by using a blood pressure cuff.
- D. Instruct the client to keep the extremity still during the procedure.
Correct answer: C
Rationale: Distending the veins using a blood pressure cuff is essential for facilitating visualization and access to the veins during IV catheter insertion. This technique helps healthcare professionals identify suitable veins, reducing the risk of complications like infiltration or hematoma formation. Using an electric shaver to remove hair on the extremity (Choice A) may increase the risk of micro-cuts and introduce infection. Selecting the antecubital area (Choice B) may not always be appropriate, as vein condition and accessibility vary among older adult clients. Instructing the client to keep the extremity still (Choice D) is important but is not directly related to preparing for IV therapy.
4. A client asks the nurse how Rituximab works, which the client is receiving to treat Non-Hodgkin's Leukemia. Which of the following should the nurse include?
- A. Blocks hormone receptors
- B. Increases immune response
- C. Binds with specific antigens on tumor cells
- D. Stops DNA replication during cell division
Correct answer: C
Rationale: Rituximab is a monoclonal antibody that binds with specific antigens on B-lymphocytes, leading to the destruction of cancer cells. In the context of Non-Hodgkin's Leukemia, Rituximab targets and destroys cancerous B-lymphocytes, which helps in treating the disease. Choices A, B, and D are incorrect. Rituximab does not block hormone receptors, increase immune response, or stop DNA replication during cell division. The primary mode of action of Rituximab is its binding with specific antigens on tumor cells, specifically B-lymphocytes, to elicit an immune response against cancerous cells.
5. A healthcare professional is reviewing laboratory findings and notes that a client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the healthcare professional?
- A. Perform immediate gastric lavage.
- B. Prepare the client for hemodialysis.
- C. Administer an additional oral dose of lithium.
- D. Request a stat repeat of the laboratory test.
Correct answer: A
Rationale: Performing immediate gastric lavage is the appropriate action for a client with severe lithium toxicity, indicated by a plasma lithium level of 2.1 mEq/L. Gastric lavage can help reduce the client's lithium level by removing the unabsorbed drug from the stomach.
