1. Protein synthesis begins with a process known as transcription. What is produced during this process?
- A. A codon
- B. A DNA helix
- C. A DNA strand
- D. An RNA strand
Correct answer: D
Rationale: The correct answer is D: An RNA strand. During transcription, the DNA template is used to produce an RNA strand, not a codon, DNA helix, or another DNA strand. A codon is a sequence of nucleotides that specifies a particular amino acid during translation, not produced during transcription. A DNA helix refers to the double-stranded structure of DNA, which is not produced during transcription. Another DNA strand is not produced during transcription since the process involves creating an RNA copy of a specific gene.
2. A female client, who is wearing dirty clothes and has a foul body odor, comes to the clinic reporting feeling scared because she is being stalked. What action is most important for the nurse to take?
- A. Assure the client that she will be seen by a healthcare provider today.
- B. Recommend that the client speaks with a social worker.
- C. Ask the client if she feels comfortable sharing why she is being stalked.
- D. Offer the client a safe place to relax before interviewing her.
Correct answer: D
Rationale: The most important action for the nurse to take in this scenario is to offer the client a safe place to relax before interviewing her. The client's disheveled appearance and foul body odor suggest she may be in distress or facing challenging circumstances. By providing her with a safe and comfortable environment to relax, the nurse can help alleviate some of her distress and establish trust. This approach is crucial as the client is already feeling scared due to being stalked, indicating underlying mental health concerns. Assuring the client that she will be seen by a healthcare provider today (choice A) may not address her immediate need for safety and comfort. Recommending she speaks with a social worker (choice B) may be beneficial later but does not address the immediate need for a safe space. Asking the client if she feels comfortable sharing why she is being stalked (choice C) is not appropriate as the priority is ensuring her safety and comfort first.
3. The nurse is caring for a client who is receiving an IV infusion of normal saline and notices that the infusion is not flowing. The insertion site is not inflamed or swollen. What should the nurse do first?
- A. Check the tubing for kinks or obstructions.
- B. Increase the flow rate to improve the infusion.
- C. Reinsert the IV catheter in another vein.
- D. Call the physician for further instructions.
Correct answer: A
Rationale: The correct first action for the nurse to take when an IV infusion is not flowing despite a normal insertion site is to check the tubing for kinks or obstructions. This step is crucial to ensure that there are no preventable issues impeding the flow of the IV solution. Increasing the flow rate without addressing potential obstructions could lead to complications such as infiltration. Reinserting the IV catheter in another vein should only be considered after ruling out tubing issues. Calling the physician for further instructions is not necessary at this stage as troubleshooting the tubing should be the initial intervention.
4. A female client with Cushing's syndrome is admitted to the medical-surgical unit. During the admission assessment, Nurse Tyzz notes that the client is agitated, irritable, has poor memory, reports loss of appetite, and appears disheveled. These findings are consistent with which problem?
- A. Depression
- B. Neuropathy
- C. Hypoglycemia
- D. Hyperthyroidism
Correct answer: A
Rationale: The correct answer is A: Depression. Depression is a common psychological manifestation in clients with Cushing's syndrome. In this scenario, the client's symptoms of agitation, irritability, poor memory, loss of appetite, and disheveled appearance are indicative of depressive symptoms rather than neuropathy, hypoglycemia, or hyperthyroidism. Neuropathy typically presents with sensory changes and motor deficits, which are not described in the scenario. Hypoglycemia would manifest with symptoms such as diaphoresis, tremors, and confusion, which are not mentioned. Hyperthyroidism symptoms include weight loss, heat intolerance, and palpitations, which are not consistent with the client's presentation.
5. A healthcare provider is assessing a client who is receiving treatment for dehydration. Which assessment finding indicates that the client is responding to the treatment?
- A. Dry mucous membranes
- B. Increased urine output
- C. Decreased skin turgor
- D. Elevated heart rate
Correct answer: B
Rationale: Increased urine output is a positive sign indicating that the client is responding to the treatment for dehydration. It suggests that the client's kidneys are functioning better, helping to eliminate excess fluid and waste products from the body. Dry mucous membranes (Choice A) are a sign of dehydration, not improvement. Decreased skin turgor (Choice C) and elevated heart rate (Choice D) are also symptoms of dehydration and do not indicate a positive response to treatment.
